Epic isn't doing that. In fact, just like China, they're trying to buy out the competition and force licenses to move over to their store. They buy exclusivity/timed exclusivity deals to rob the Steam and other stores of sales.
Really, this is the biggest issue for me. I'd love to see more competitors (and, in fact, will preferentially purchase most things on GoG over steam, simply because you can get the backup files for them). But, when Epic started doing the "buy out the devs to lock the game to just Epic for a year" - especially when nearly all of the games (if not all) they did that on had said they were doing a Steam release before Epic came along with a Scrooge McDuck bag - then it's time to nope out.
