I switched to self-hosted Vaultwarden and it was so trivial. I had it set up and switched in literally like 10 or 15 minutes. The ability to export your vault from any of your devices makes it less of a concern that you might accidentally wipe your Vaultwarden DB and be screwed, and you don't even need to add surface area by exposing it to the internet if all your devices log onto your local network occasionally.

Originally I was okay kicking $10 to Bitwarden as a sort of donation, but them doubling the fee for dubious "ooh fancy smart scanning tech" just seems like them wanting more money, or at least misusing the money that they have. If they polled users to ask "do you want to spend double the fee for us to do smart scanning?" I guarantee they would have gotten a resounding 'no'.
