Why not Windows
Windows and Office work fine — Why worry about it?
By using these products, we have to agree to a number of harsh restrictions. For most Windows licenses, you can't keep the software when you change the hardware. You sometimes can't even give your software away. Who can run the software? On which computer? What can you do with it? The list of restrictions is long and some items are outrageous.
Why are Office documents difficult to export? Why are the formats continually changing? Why can you not even uninstall some programs? It might be that if you look for choice, Microsoft products aren't for you.
If you can't get a right to inspect source code (the human-readable inner workings of a program), you can't have someone correct flaws or evaluate how your privacy is protected for you.
And guess what? On software that comes with source code, viruses and spyware aren't effective, and security isn't bought on extra. The antivirus software industry, in which Microsoft is now a significant player, prefers you to use Windows.
Computers are used to share ideas, culture and information. Without these freedoms over software, we risk losing control over what we share.
This is happening today. From plain annoying technologies such as Digital Restrictions Management (DRM) to downright frightening ones like Trusted Computing, everyone's ability to participate in culture is threatened.
If you have to give up your freedoms to use software, maybe you should not be happy with it.
Many people find that Windows, an otherwise decent piece of software, withdraws so many rights from them, that it is not worth them using it. Mac OS is not much better, either.
