I looked through the official server. 96 out of 1680 files were located in the bitwarden_license directory, so I'd say a lot less than "half" the official server. Nonetheless their web offering is still non-free, and from hearing about the difficulties self-hosting, it's probably a bad idea.
However I don't know whether I'm better off using Bitwarden free, paid, self-hosting and managing backups myself, or just sticking with Firefox Sync (which has a truly awful barely-working Android app).
