I like to support devs who makes great products, excellent ones like bitwarden. Otherwise they will go away and we will be left with big tech products only. Because I don't think people like to make excellent products and still don't see a dime in their pocket.
I like to support devs, too - But I don't like being forced into paying for access to features already present in software that is running on my own hardware. The code is already on my machine, I should be able to run it.
That's my biggest complaint about Bitwarden - I want to share passwords with my wife, and they want to charge me money for that even when I host it myself.
It is open source - but the server essentially locks you out of various functionality unless you create an account with Bitwarden and provide a valid subscription token.
If I were to selfhost bitwarden again, I'd go with Vaultwarden, which claims to be fully compatible and has no such requirements.
