For reference, Twitch has invested very heavily in anti adblockers and it’s pretty difficult to sidestep the ads these days without paying $5/month for a subscription.
Compare this to streaming on YouTube, which has a (much) worse UI, but tolerates ad blockers and lets you watch the parts of the steam you missed. I’m not optimistic that Twitch will be able to survive if YouTube manages to get their shit together and make a half decent UI.
