I might be mistaken but, I think cellular carriers force 480p. I always use a VPN and PipePipe, LibreTube, or Clipious so, I don’t know for sure. Lol And, I do look for PeerTube content sometimes.
Yeah, I don’t think any of the “creator” advert things you mentioned have much to do with the big G. I’d guess that 70% of that goes to the channel. Hopefully that much or even more.
Either way, as someone who makes music and goes to local shows, I generally avoid YT and other big platforms. I encourage other bands to upload to PT and FunkWhale. They may as well upload torrents with how much artists get paid from streaming, and use whatever third party tipping platforms.
