Everything and everyone. Seriously, even the people making literally millions on twitch hate the DMCA takedowns, the completely capricious bans, the ridiculous barrage of forced ads which twitch has straight up lied about, the fact that Amazon streamed anti-union ads on twitch and then pretended it was an accident, the fact that titty streamers get special priveleges...and that's what I thought of in just 30 seconds off the top of my head.
twitch is fucking awful because it's owned by Amazon. It was great before the acquisition and shortly thereafter.
I never said it was easy. I'm saying twitch fucking sucks and when somebody makes something that doesn't suck it will instantly be an 11 digit market cap company. Right now the most likely contender is Gamestop, even if I'd only put that at about a 1% chance of happening.
