I'm guessing that their job at Google allocates a significant percentage of their time to work generally on open source Git, with the rest on Google-specific needs and deployments like googlesource.com. This post on Google's open source blog fits squarely in the overlap of both. As well, most of Google's releases in the developer tools, open source, or Cloud Platform worlds don't have ads - indeed GCP is an entire revenue stream not dependent on ads. Source: Much of my day-job work on my last team at Google was open source on the GCP team, and I also got approval to own some side-project work done on my own time. So I got to see how they handle such things. I don't have specific knowledge of the Git team's arrangements, but this is an educated guess.
