I find this move concerning, and wish that the Founder had looked for a new CEO that shared his values rather than a Private Equity and Mergers Expert.
Furthermore, the change to the GRIT motto is worrying. Trust is useless without Transparency when it comes to code and security.
Well, the client code is liensed GPL 3.0 and server code is licensed AGPL 3.0, and those are both FOSS licenses. There are some additional commercial components licensed under a non-FOSS source-available license, but those are not required for the basic service. I guess you can’t use the Bitwarden trademark either. I would still consider Bitwarden FOSS, although with a slightly limited (but not crippling) scope of the term “Bitwarden”.
