Pull request #10974 introduces the @bitwarden/sdk-internal dependency which is needed to build the desktop client. The dependency contains a licence statement which contains the following clause:
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.
This violates freedom 0.
It is not possible to build desktop-v2024.10.0 (or, likely, current master) without removing this dependency.
None of that makes Bitwarden not open source. Not only that, they specifically state this is a bug which will be addressed.
I would go as far as to say that Bitwarden’s main competitive advantage and differentiation is that it’s open source. They would be insane to stop that.
Yes, it does, because it violates its own license GPLv3 by having proprietary build-/runtime dependencies.
If it was under a different, maybe more permissive, open source license, then maybe it would still be open source, but as of right now i likely breaks its own license terms.
From what they state, they think that because executables that share internal information via standard protocols does somehow not break GPL3 terms compared to two libraries that share internal state via the standardized C ABI which does. And they seem to not consider that a bug, just the build-time dependency.
Sorry that’s my mistake - I should have said “source available”, rather than “open source”. IMO, being source available is the critical component of a password manager like Bitwarden, and is what I meant when I referred to their main competitive advantage.
They might also choose to be open source and fix this specific issue and return to GPL-compatibility, but remaining source available would seem to be the more critical factor.
So you meant to say:
That is not true, there are a lot of other password management software out there where the client source code is either open source or source available. For instance keyguard: https://github.com/AChep/keyguard-app?tab=License-1-ov-file#readme which is an alternative proprietary bitwarden client, where the source is also available. Also the Proton Pass client is under GPLv3.
I would argue that the main advantage of bitwarden compared to others is that it is open source and has an open source server for self-hosting (vaultwarden). Which of course makes it difficult in terms of business strategy with their VC funding. But maybe becoming a non-profit org and getting money from donors, the strategic funds of EU and other governments, etc. might be an alternative way.
I’m not aware of any other enterprise password management where the server source is available and auditable. Proton certainly is not.
