Just because there are far more Windows users than Linux users (not that that has ANYTHING to do with this, lots of Windows users use Firefox for example) doesn't mean the minority group won't be able to massively upvote something out of control. It's not like everyone votes, only a small minority vote - and guess who are more likely to vote? People who feel strongly (for or against). So if there are more haters than there are people who care to fight the haters, guess who "wins" the vote?
