It's not discontinued: https://docs.github.com/en/enterprise-server@3.12/admin/all-...

Well, I didn't stipulate, so you got me on a technicality thanks to English ambiguity, but I submit that "gave" does not imply "contact sales".

Also my error for saying self-hosted when that was never the most important property.

I don't think it's discontinued, you just linked to a version that's outside of its support window.
