Cloning YouTube is foolish. The future is decentralization. Another example of this is how Gab tried to just be twitter for conservatives without actually doing anything new, whereas the fediverse takes the power away from one company/server and makes it easy to host your own instance with rules of your choosing. On the video side we've got PeerTube and a few others. I'm hesitant to list a bunch without recalling their exact feature set, but there's also DTube and BitChute.
