Yes. That's the trick big corps play on you. They develop some code, and push it to GitHub.

- all of the decisions where the code is going belong to the corp

- all (or at the absolute vast majority) of contributions come from the corp's developers

- there's little to no insight into why things are the way the are. Sometimes you can be big enough to gain acces, or important enough. Before "open governance" it was some publisher group set up by Google that was supposedly there to monitor

But sure, it's open source.

> Pull Requests are accepted from anyone and those changes land in Google production

1. What's the ratio of PRs from Google employees to those from "anyone"?

2. Indeed. They land in Google production. The company with $183 billion in yearly revenue thanks you for your unpaid contributions (if they ever make it)

BTW, there are 1 500 open issues in that repo. Quite a lot for some validation rules.
