The friends that I game with started using Discord for some reason. Most of the games we play have in-game VOIP. If not, Steam worked fine, but for some reason they decided we need more bloat installed. I don't like it. I don't trust it. You know what they say about free shit; if you're not paying for it, you're not a customer, your the product. They'll leave it running 24/7, but I only launch it when we're using it and shut it down when done. Quite often after shutting it down, I'll hear my CPU fans kick in when the PC is idle. I look and find a couple of discord processes still running and doing who knows what. I don't recall it ever crashing on me though.
