This is clearly something done in official capacity, during working hours, with the knowledge and support of his manager, who announced the CLI.

It says "This is not an officially supported Google product" because it's a DevRel sample/experiment, just like dozens of other Google repositories made by Google employees as part of their job.

Even some other tools in github.com/google have as much: https://github.com/google/python-fire / https://github.com/google/pytype/blob/main/docs/index.md / https://github.com/google/dopamine / https://github.com/google/go-tika

That's because from what i gather so far it is a google repo with other tools using the same api they kept it in there since and even had it announced by the guy's manager at the time.

tbh i assumed that is an official product too

You know this GitHub account might be more official than I thought? Maybe the problem is more to do with their approval process, which I guess negates a lot of my comments.
