So, a friend of mine wants to become a Twitch streamer, commenting over movies. I never used Twitch. He showed me some channels over there that made me confused. There are dozens of channels entirely dedicated to people providing minimal commentary to entire movies, animes, and TV shows which are displayed in full, although not on full screen. And they seem to be monetized, otherwise why would anyone stream 5 to 10 hours a day? They have ads.

I have a few questions.

First, how is that legal? Why aren't copyright holders taking these channels down? Do people really care about a streamer that mumbles a single uninteresting word every few minutes, or it's all just an excuse to watch movies for free? Why the same content that will get your video taken down on YouTube is apparently okay on Twitch?
