Yes for all except youtube. I use frontends there. LBRY when feasible and there’s not a lot of content creators on PeerTube at least we got “The Linux Experiment”. PeerTube needs a monetization model imo (benefiting content creators and instance hosters). I wouldn’t mind paying a low fee for watching content for instance.
Sounds like a decent approach. Private by default but without taking away the freedom to interact with threads if so desired. At worst an inconvenience
