You must read this article by Richard Stallman on the BCC News website about Bill Gates retirement (BBC article). Richard Stallman is the founder of the Free Software Foundation and from the article you can see that he sees Microsoft as and Bill Gates as Dark Vader.
I agree with his argument about the Microsoft Tax which large suppliers have on their ready to use PC’s. You should be able to decide what you use on your hardware and if you use Linux you shouldn’t be paying for Windows. The question is; does the average buying/user really care what OS he or shee is using. I think most of them are thinking; as long as my applications I want to use are running and I don’t have to bother about the other stuff, I don’t care.
More interesting is to see how deep the founder of the organisation of the Free Software Foundation is in the trenches and is unwilling the move. All companies are wicked and have control over your freedom. The only way is free and open software.
I personally think these is a place for open and proprietary software.
