Free for All by Peter Wayner (good books to read for young adults .TXT) 📕

and about $2,500 for Applixware, an office suite that does much of the same job as Microsoft Office. A truly cheap and technically hip office could make do with the editor built into Netscape and one of the free spreadsheets available for Linux. It's not hard to imagine someone doing the same job for about $3, which is the cost of a cheap knockoff of Red Hat's latest distribution.

Of course, it's important to realize that free software still costs money to support. But so does Microsoft's. The proprietary software companies also charge to answer questions and provide reliable information. It's not clear that Linux support is any more expensive to offer.

Also, many offices large and small keep computer technicians on hand. There's no reason to believe that Linux technicians will be any more or less expensive than Microsoft technicians. Both answer questions. Both keep the systems running. At least the Linux tech can look at the source code.

The average home user and small business user will be the last to go.

These users will be the most loyal to Microsoft because they will find it harder than anyone else to move. They can't afford to hire their own Linux gurus to redo the office, and they don't have the time to teach themselves.

These are the main weaknesses for Microsoft, and the company is already taking them seriously. I think many underestimate how bloody the battle is about to become. If free source software is able to stop and even reverse revenue growth for Microsoft, there are going to be some very rich people with deep pockets who feel threatened. Microsoft is probably going to turn to the same legal system that gave it such grief and find some wedge to drive into the Linux community. Their biggest weapon will be patents and copyright to stop the cloners.

Any legal battle will be an interesting fight. On the one hand, the free software community is diverse and spread out among many different entities. There's no central office and no one source that could be brought down. This means Microsoft would fight a war on many fronts, and this is something that's emotionally and intellectually taxing for anyone, no matter how rich or powerful.

On the other hand, the free software community has no central reservoir of money or strength. Each small group could be crippled, one by one, by a nasty lawsuit. Groups like OpenBSD are always looking for donations. The Free Software Foundation has some great depth and affection, but its budget is a tiny fraction of Sun's or Microsoft's. Legal bills are real, and lawyers have a way of making them blossom. There may be hundreds of different targets for Microsoft, but many of them won't take much firepower to knock out.

The free software community is not without some deep pockets itself. Many of the traditional hardware companies like IBM, Compaq, Gateway, Sun, Hewlett-Packard, and Apple can make money by selling either hardware or software. They've been hurt in recent years by Microsoft's relentless domination of the desktop. Microsoft negotiated hard contracts with each of the companies that controlled what the user saw. The PC manufacturers received little ability to customize their product. Microsoft turned them into commodity manufacturers and stripped away their control. Each of these companies should see great potential in moving to a free OS and adopting it. There is no extra cost, no strange meetings, no veiled threats, no arm-twisting.

Suddenly, brands like Hewlett-Packard or IBM can mean something when they're slapped on a PC. Any goofball in a garage can put a circuit board in a box and slap on Microsoft Windows. A big company like HP or IBM could do extra work to make sure the Linux distribution on the box worked well with the components and provided a glitch-free existence for the user.

The hardware companies will be powerful allies for the free software realm because the companies will be the ones who benefit economically the most from the free software licenses. When all of the software is free, no one controls it and this strips away many of Microsoft's traditional ways of applying leverage. Microsoft, for instance, knocked the legs out from underneath Netscape by giving away Internet Explorer for free. Now the free software world is using the same strategy against Microsoft. It's hard for them to undercut free for most users.

The university system is a less stable ally. While the notion of free exchange of information is still floating around many of the nation's campuses, the places are frighteningly corporate and profit-minded. Microsoft has plenty of cash at its disposal and it hasn't been shy about spreading it around places like MIT, Harvard, and Stanford. The computer science departments on those campuses are the recipients of brand-new buildings compliments of Bill Gates. These gifts are hard to ignore.

Microsoft will probably avoid a direct confrontation with the academic tradition of the institutions and choose to cut their prices as low as necessary to dominate the desktops. Universities will probably be given "free," tax-deductible donations of software whenever they stray far from the Microsoft-endorsed solution. Lab managers and people who make decisions about the computing infrastructure of the university will probably get neat "consulting" contracts from Microsoft or its buddies. This will probably not mean total domination, but it will buy a surprisingly large amount of obedience.

Despite these gifts, free software will continue to grow on the campuses. Students often have little cash and Microsoft doesn't get any great tax deduction by giving gifts to individual students (that's income). The smartest kids in the dorms will continue to run Linux. Many labs do cutting-edge work that requires customized software. These groups will naturally be attracted to free source code because it makes their life easier. It will be difficult for Microsoft to counteract the very real attraction of free software.

Of course, Microsoft is not without its own arms. Microsoft still has patent law on its side, and this may prove to be a very serious weapon. The law allows the patent holder the exclusive right to determine who uses an idea or invention over the course of the patent, which is now 20 years from the first filing date. That means the patent holder can sue anyone who makes a product that uses the invention. It also means that the patent holder can sue someone who simply cobbles up the invention in his basement and uses the idea without paying anything to anyone. This means that even someone who distributes the software for free or uses the software can be liable for damages.

In the past, many distrusted the idea of software patents because the patent system wasn't supposed to allow you to lay claim to the laws of nature. This interpretation fell by the wayside as patent lawyers argued successfully that software combined with a computer was a separate machine and machines were eligible for protection.

Today, it is quite easy to get patent protection for new ideas on how to structure a computer network, an operating system, or a software tool. The only requirement is that they're new and nonobvious. Microsoft has plenty of these.

If things go perfectly for Microsoft, the company will be able to pull out one or two patents from its huge portfolio and use these to sue Red Hat, Walnut Creek, and a few of the other major distributors. Ideally, this patent would cover some crucial part of the Linux or BSD operating system. After the first few legal bills started arriving on the desk of the Red Hat or Walnut Creek CEO, the companies would have to settle by quitting the business. Eventually, all of the distributors of Linux would crumble and return to the small camps in the hills to lick their wounds. At least, that's probably the dream of some of Microsoft's greatest legal soldiers.

This maneuver is far from a lock for Microsoft because the free software world has a number of good defenses. The first is that the Linux and BSD world do a good job of publicizing their advances. Any patent holder must file the patent before someone else publishes their ideas. The Linux discussion groups and source distributions are a pretty good public forum. The ideas and patches often circulate publicly long before they make their way into a stable version of the kernel. That means that the patent holders will need to be much farther ahead than the free software world.

Linux and the free software world are often the cradle of new ideas. University students use open source software all the time. It's much easier to do way cool things if you've got access to the source. Sure, Microsoft has some smart researchers with great funding, but can they compete with all the students?

Microsoft's ability to dominate the patent world may be hurt by the nature of the game. Filing the application first or publishing an idea first is all that matters in the patent world. Producing a real product is hard work that is helped by the cash supply of Microsoft. Coming up with ideas and circulating them is much easier than building real tools that people can use.

The second defense is adaptability. The free software distributions can simply strip out the offending code. The Linux and BSD disks are very modular because they come from a variety of different sources. The different layers and tools come from different authors, so they are not highly integrated. This makes it possible to remove one part without ruining the entire system.

Stallman's GNU project has been dealing with patents for a long time and has some experience programming around them. The GNU Zip program, for instance, was written to avoid the patents on the Lempel-Ziv compression algorithm claimed by UNISYS and IBM. The software is well-written and it works as well as, if not better than, the algorithm it replaces. Now it's pretty standard on the web and very popular because it is open source and patent-free. It's the politically correct compression algorithm to use because it's open to everyone.

It will be pretty difficult for a company like Microsoft to find a patent that will allow it to deal a fatal blow to either the Linux or BSD distributions. The groups will just clip out the offending code and then work around it.

Microsoft's greatest hope is to lock up the next generation of computing with patents. New technologies like streaming multimedia or Internet audio are still up for grabs. While people have been studying these topics in universities for some time, the Linux community is further behind. Microsoft will try to dominate these areas with crucial patents that affect how operating systems deal with this kind of data. Their success at this is hard to predict. In any event, while they may be able to cripple the adoption of some new technologies like streaming multimedia, they won't be able to smash the entire world.

The third and greatest defense for the free source ideology is a loophole in the patent law that may also help many people in the free software world. It is not illegal to use a patented idea if you're in the process of doing some research on how to improve the state of the art in that area. The loophole is very narrow, but many users of free software might fall within it. All of the distributions come with source code, and many of the current users are programmers experimenting with the code. Most of these programmers give their work back to the project and this makes most of their work pretty noncommercial. The loophole probably wouldn't protect the corporations that are using free software simply because it is cheap, but it would still be large enough to allow innovation to continue. A non-commercial community built up around research could still thrive even if Microsoft manages to come up
