That's not exactly what happened, they pushed more of their code into their own library that was not permissively licensed but then they open sourced it so the issue was resolved. https://github.com/bitwarden/clients/issues/11611#issuecomment-2436287977

You're kidding right? The Steam client is overflowing with features, beyond the nice and simple mod manager, multiplayey systems for easy joining it also has a full featured discord alternative inside the chat system with voice and text chat and I think even screen sharing. To compare it to Xbox achievements is just insane for how much the steam client provides.
