What's up with Epic Games?

I can't seem to find that one comment explaining the issue with them...

But for the sake of promoting conversation on Lemmy, what's the issue with Epic, and why should I go for Steam or GoG?

Note: Piracy is not an answer. I understand why, and do agree to a certain extent... But sometimes, the happiness gained by playing something from a legitimate source is far greater 🥹... coming from someone who could never ever afford to purchase games, nor could my parents... Hence I've always played bootleg, or pirated games.

TL;DR

What's wrong?

• Their launcher has a terrible UI AND UX.
• They make exclusive deals with studios to prevent other platforms from getting games. (Someone mentioned that Steam did the same thing in their infancy. Also, I have another question; why is it ok for Sony and Microsoft to make exclusive games for their consoles but not ok for these PC platforms to do so?)
• They have been invested in by a Chinese company, Tencent. (Someone mentioned that it isn't that big of a deal, but idk.)
• They are actively anti-linux for some reason.
