I've worked for several Fortune 500 companies. Support has nothing to do with the decision: Exclusionary contracts do. Microsoft offers huge discounts to businesses that agree not to use a competitor's product. They also regularily check for compliance and there are large fines for any company caught using open source software.
I have been an employee/contractor at many Fortune 500 companies, and have never seen anything even hinting at a contract with Microsoft involving "large fines for any company caught using open source software". Care to provide any proof of Microsoft contract with any F500 consumer of software that prohibits said F500 from running open source software?
Seriously though, the poster you're responding to is full of shit. I've been in IT for 25 years and have worked with everything from SMB's to Fortune 10's and have never seen any such thing.
It would be nice if people could state their opinions without resorting to lies and trolling.
And I guess based on the conclusions of you two,
The Emperor of Japan doesn't exist, since you haven't met him
The damage caused by the tsunami in Indonesia doesn't exist cause you weren't there when it happened.
A tree fell in the woods and it made no sound. Cause you didn't bless it with your presence.
Maybe if you two would do some REALLY LIGHT googling, you'd see that what he said is correct.
Maybe not wide reaching nor at every place but there were collusive and exclusive deals laid out
by Microsoft "back in the day", that guaranteed Linux would not take foothold.
Not everyone has to prove what you don't know, lol. They make encyclopedias for that.
