Great heads up! I will work on self-hosting this month.
But, the main developer of works at Bitwarden.
Thankfully you can easily export your passwords and move to another system (unlike say Authy where we had to inject Javascript to extract the TOTP seeds).
I would still recommend switching to Vaultwarden. With Tailscale you don't have to expose it to the outside world.
Just keep a copy of the export somewhere else.
I like my export unencrypted and move it to a location that is encrypted.
Separately, I don't know if there is a self-hostable password manager which allows easy family sharing. (KeepassXC won't work, I believe, because the whole vault is a single file.)
