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.
That “explanation” is unsatisfactory and likely wrong: https://www.gnu.org/licenses/gpl-faq.html#MereAggregation
So they either have to license their SDK under a GPLv3 compatible license, or switch the license of their client to a non-GPL one.
Their “explaination” only mentions why they think can do it, but not why they are doing it.
That may or may not be the case, but the comment I replied to said they locked the thread with “no explanation”.
