MS releases everything on both of their platforms? Oh, how charitable of them.

So it’s fine if it’s small enough and affects less people (Xbox users)?

No.

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.
