Microsoft never wants to actually compete on merit.
Their monopoly is built on the fact that the PC user community was short-sighted enough to let MS proprietary "standards" become de facto public standards.
Now MS wants to use the threat of patent enforcement to deter Linux. What a crock! I'll bet MS "borrowed" far more from unix than vice versa. Now they want to play this little game where they claim IP infringement but refuse to say what the infringing code is. Baloney! That's comparable to a shop owner accusing you of shoplifting but refusing to say what it is you actually shoplifted!
The whole idea that "free" software is somehow "anti-capitalistic" is nonsense, by the way -- unless you think that breathing air without paying for it is anti-capitalistic too!
No, I don't think so. That would make the MS executables WAY too small and efficient.
Here's something interesting...
Open up any copy of ftp.exe in Notepad and scroll down a bit.
It states Copyright (c) 1983 The Regents of the University of California
Yep, my guess is they lifted virtually the whole TCP/IP stack right from BSD Unix...
