It wasn't, but they aren't forcing banks on the store either (they HAVE done it with other companies, I'm not debating that).

And most of the time PC leads to multiple releases as platforms tend to make it as easy as possible to release across multiple.

Sure the majority of games are on one but a significant fraction of the popular ones are on multiple.
