unless PeerTube finds a way to pay content creators
Google is a for-profit organization. Framasoft, which developed PeerTube, is a non-profit one. The only way to pay content creators is when people donate money to PeerTube and then PeerTube share that money with creators. Which is also difficult because there are no trackers to know internally who has more subscribers or which video has more views, etc. Internally as using a tracker, but you have to visit one by one every channel and every video to know its numbers.
