"You may not use this SDK to develop applications for use with software other than Bitwarden (including non-compatible implementations of Bitwarden) or to develop another SDK."

Because they aren't focused on just one single service. Bitwarden is a single business only focusing on their password manager, whereas proton has a suite of tools. Passwords need to be stored absolutely in a robust and safe way. I don't trust proton with anything at all, and the proton pass is no exception. The client might be open source, but the backend is not. It's also not as mature as bitwarden.
The server is not open source and I wouldn't trust a business that is not just working on password managers.
That is the bare minimum of a password manager like Bitwarden.
