I guess for the privacy conscious and content creators, one solution of this would be to host your own instance just for yourself.
That's exactly what I did. Have it running in docker containers at a VPS provider for $5/month and ship backups off to Backblaze nightly.
Never have to worry about my "home" instance dying/suddenly disappearing or defederating other instances. I like to self-host when it makes sense to, and this is definitely a situation where it makes sense.
