> Why isn't it under google's username on github?

It's under "googleworkspace", one of Google's GitHub organizations (linked on https://developers.google.com/workspace).

> Why does the repo say "This is not an officially supported Google product."?

This seems to be boilerplate that Google puts on open-source releases, e.g: https://github.com/GoogleContainerTools/kaniko

It's not saying that it's not released by Google, but that it's not an officially supported Google product. I presume to make it clear that it's not covered by support agreements/bug bounties/etc. in the way products like Google Docs would be.

> Is it actually approved by Google or not?

It went through the launch/approval process (https://news.ycombinator.com/item?id=48655744) and was announced by Justin's manager.
