Google Workspace is but the CLI is not. These are 2 related but different products. Had he just released it under his name then that wouldn't have been such a big issue, maybe, but he used the Google logo which implied it was Google blessed. If I did the same thing, they would have a case for suing me. Just because you work for Google does not mean you can release products under their name. Google spends countless of man-hours to make sure whatever product they put out is as good as possible. And support it on any issues that are found along the way. All companies protect their logo to a high degree simply because of the implications it has when people see it.

I mean, the GP is being overdramatic but releasing a vibe coded cli frontend for an official product in a google github org and that uses your google account credentials is a big deal no matter how unofficial you claim it is in the readme.
