Plus, they have that little paperclip thing that pops up whenever you ask for help...
That's completely nonsensical. Microsoft didn't act anti-competitively to become big, they did it AFTER becoming big. You can't abuse power you don't have, and when Microsoft won the OS contract with IBM, it was a tiny company, and Apple was by comparison huge.
Microsoft got big by taking advantage of the fact that the guy that wrote DOS didn't think it was worth anything, so he was happy with the $50k (or whatever) that Bill gave him for it, and IBM didn't think that the PC market would go anywhere, so they didn't think anything of giving MS money for every PC sold.
When Bill started licensing DOS to every company that wanted to make a PC, Microsoft became big.
THAT is how Microsoft acquired the power to abuse that they then proceeded to abuse.
I didn't say that's how they got started, but rather one of the ways that allowed them to reach the size they are today. Even if you know nothing of the antitrust case, you'd have to admit some shady stuff was going on when you see a browser like IE6 last so long :p
