Does it help you to know that if Microsoft were ever stupid enough to do that, it wouldn't EXIST a few monhts later? It is accepted business reality that the only thing that has saved MS from being chopped up into tiny piece years ago is the continued existence of Apple. Without Apple, MS's market share is essentially 100%. That is a monopoly, and no White House to the left of Harry Browne would put up with it for a second.
Doesn't Linux now own a bigger share than Apple (which hovers around 5%)? Last I saw, Microsoft owned about 87% of the market. Apple's share is a spit in the ocean.
