Why Does Everyone Hate Microsoft?

MrSplog asks: "I'm doing a short project on Microsoft and its impact on society. A considerable part of this project has been looking into people's perceptions of Microsoft and the heavily negative bias of that perception. Since Slashdot is one of the world's forefront leaders on Microsoft hatred, I wanted to know: just why do you hate Microsoft? Please be as descriptive and as thorough as you like. Counter arguments and positive comments are also appreciated."
