For some clarity on the support here: at Google it’s very easy to publish arbitrary code on the Google GitHub, and a bit of a pain to get permission to publish (new) projects on your personal GitHub. It’s also not too tricky to take a project with you (i.e. transfer ownership) if you leave. For these reasons, many googlers just publish their hobby projects on GitHub under the Google org. That’s most likely what this is, the support disclaimer is the big giveaway.
