I use the open source bitwarden server vaultwarden, but still use the official browser plugin and Android app - though I wonder if this library license change would affect open source client implementations by requiring third party extensions and apps to implement their own compatible BitWarden API. The cynic in me wonders if that could be a move to make it harder on developers of third party clients in an effort to strengthen the position of the official clients even when using a third party server like vaultwarden. I never really considered using a foss bit/vaultwarden browser extension or Android app but maybe I should if it exists.

Someone correct me if I’m interpreting the license issue wrong.
