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".
