Specifically it's more of a peace of mind thing with regard to security. I actually do use Bitwarden though (bitwarden_rs container) and although the critical info in the database is encrypted, I worry less about my network getting hacked than a high value target such as a hosted password manager. It is for this same reason that I don't save passwords in the browser and defer to my locally running password manager. Note that for non-technical people, using a hosted password manager is far preferable in most cases than not. And for technical people who don't want to go through the effort of standing up their own service, paying for somebody else to do it for you is no doubt easier. It is nice that when you self-host you also don't have to worry about a third party service shutting down. But for security oriented software I think it'd be too risky to continue running indefinitely without maintenance, so unless people stepped up to maintain the code you'd only be buying yourself your own migration timeline really.
