This guy clearly does not knows anything about cygwin and mingw. Yet still there are some programs which you cannot run but that is due to lack of features in windows (signal and ptys) rather than an evil Microsoft scheme.

What the author does not understands is that this clause (3.3.1) was originally absent from the agreement and was added for sole purpose of pissing off Adobe. That is anti competitive for sure. IMHO its equivalent to what MSFT tried to do when it started distributing IE for free.
