Why do people always say they really hate Microsoft?

I never quite got that one. It’s a trend amongst net people to claim they really hate Microsoft. And most of them use Windows themselves, which is so ironic it’s stupid. If you really hate Microsoft and/or Windows, don’t use their products, problem solved. And even if you don’t use their products, why would you really hate Microsoft? I guess it’s some kind of trend, people say it to appear ‘cool’.
I myself use Windows XP and am very satisfied with it. It has never crashed on this comp that I’ve been using for a few months, for instance. And I think it’s a great OS all-around. Some of their other products may be crap, but that’s why we don’t use said products.
The only thing that I really hold against Microsoft is Internet Explorer. Sure, I don’t use it, but I’m a web designer and the fact that they refuse to comply with the w3c and other standards makes life a lot harder for us designers. Really, designing a site (I’m talking about HTML with CSS generally, not Flash) has become something like 50% work to make the site and then 50% work to make it look and operate correctly in Internet Explorer.
But otherwise, people who say that Microsoft and Windows suck and that they hate thrm, but then always use Windows and probably MS Office just amaze me.
