Mention services server code availability

[jerm]

Oh, I didn’t mean it as criteria, but rather just mentioning it in their recommendation page. Like they mention that Bitwarden server code is open source

Bitwarden’s server-side code is open source, so if you don’t want to use the Bitwarden cloud, you can easily host your own Bitwarden sync server.

But they don’t mention if the service’s server code is closed source; it is inconsistent.
