WebRTC could be used to provide peer-to-peer streaming. The load on the servers would be very minimal since the feeds would be sent directly from the host to the viewers. A lot of live streaming and video conferencing apps already use it to keep their hosting costs down.
The downside is that the IP address of the viewers will be exposed, even over a VPN unless precautions are taken by the user or the application.
I quit a long time ago without even meaning to.
There was just less and less content to keep me interested while more ads and "recommendations" kept taking their place. At some point I was just forcing myself to open the app each day and just stopped.
If an app, website, or game won't respect my time, why should I give it any?
