I'd love steam to have some competition. epic isn't it though. Epic sucks up your personal data to sell to advertisers and "marketing partners", the client itself is trash, it's just one more middle man to get in your way (https://old.reddit.com/r/EpicGamesPC/comments/zc5ri3/playing...) at inconvenient times.

A good competitor would not come from a game publisher. It wouldn't collect any more data than it needs and wouldn't use your data for marketing or sell it to anyone else. It also wouldn't be able to remove your ability to access and play the games you've already purchased for any reason.

Bad products/services that are more trouble than they are worth do not magically become good because they might compete in some ways with something else.

GoG is the closest thing to a steam competitor right now and even in that case I have zero incentive to install their client.
