Sure, but the initial assertion was that only the client was open source which is clearly false, so I was refuting that. I did not speak the the FOSS nature of the software.
The Bitwarden server is source-available, but not open source. This is because, for example, section 2.3 of the license agreement (https://github.com/bitwarden/server/blob/master/LICENSE_BITW...) conflicts with section 6 of the Open Source Definition (https://opensource.org/osd), titled No Discrimination Against Fields of Endeavor. I think the specific terminology is what others here are disputing.
The Bitwarden desktop and mobile clients are open source because they are under GPLv3, a license that meets the OSD. Vaultwarden is also GPLv3.
