Sounds to me like there is a future Fediverse advocate in the making right here!
https://en.wikipedia.org/wiki/Fediverse
The Fediverse is made up of separate open source social softwares which are interconnected through their shared ActivityHub protocol.
People who want to gather and discuss in communities online deserve a place to do it without admin oversight / for profit influence / advertiser influence / opaque moderation, regardless of how anyone in position of authority feels about it.
There already exist some fantastic platforms which are analogs for popular social media, including...
Lemmy, which operates similar to Reddit
Mastodon, which operates similar to Twitter
Matrix, which operates similar to Discord
PeerTube, which operates similar to YouTube
...and that is just a few! This is truly the future of online communication, in my opinion.
I also started an 'Open Source' community on this instance to discuss both federated and other open source software.
