People want to strike at the machine that is M$ due to several reasons.
You'll also notice the overwhelming majority of those people are still using windows and not linux, as they'll say due to "software compatibility", which is true.
This is what I figure: Is there one product out there that is stable enough to be used in day to day tasks and has a large software library. Yes. That product is made by M$.
In addition, I'm not sure what you consider support for M$ on this forum.
Explain.
The people seeking help in this forum concerning Windows don't know what linux is or don't care and more importantly don't need/want to know or care.
