Sony buying everything is just as much a problem as MS doing it. I think the main difference is that they've stayed under the radar by doing smaller purchases, but I want someone to push the brakes on them equally as much.

Microsoft can do that by actually competing. Throwing money around solely to take things away from people who don't buy their products to entrench themselves in the market is anti-competitive. Allowing that sort of thing means any behemoth can come and muscle their way into any market they want to. This is a bad future.
