Imagine using this energy for actually productive change, over being angry that you're being slightly inconvenienced.
Pretty much what happened is it wasn't advertised that you would need an epic games account to play the multiplayer, and people are angry about it for some reason. Likely because it's Epic, not because they had to make an account, though knowing Gamers they probably would be pissed about about having to make an account outside of steam too.
And it's funny because the one discord server I usually hang out on that has pretty chuddy people on it largely had a reaction of "Sure it sucks, but there's a lot bigger fish to fry in the games industry."
hey, finally some time to play a game! how about Big 3A Sandbox 2018, haven't played that in a while
huh, let's just let steam update it, just three minutes
ok now it's starting
oh another launcher
oh, launcher needs to update, just four more minutes
ok finally done, but now i need to log into my PublisherOnline account, just let me reset my password that i haven't used in forever
ah, now it's connecting to PublisherOnline, almost there
oh sweet, PublisherOnline launcher .exe crashed, that's 25 minutes well spent
