They have been in hot water before when they were caught scraping data without consent and sending it back to Epic. Folders/files and apparently steam user info?

The client still supposedly phones home with some encrypted data and nobody is completely sure what it is, they say it's anti-cheat stuff, but then there's this:

"40% of Epic Games is owned by Tencent they're a Chinese Tech Company which the Chinese Government has a certain say in what they do. LITERALLY without Tencent Epic would go under they're the only reason why Epic Games has gotten so many exclusives and given away so many free games. There is LITERALLY a board member in Tencent that was appointed by the Chinese Government."

So can we trust them? Probably not.

Some people don't like having to use more than one launcher. Some people don't like Epic buying out games and making them exclusive to EGS (which keeps the price artificially high for longer). Some people just feel like the launcher, er, launched without feature parity with Steam, and has made very few improvements since launch. I'm sure there's more reasons people dislike Epic. I don't overly care but it's certainly not a preferred platform for me.
