Same for intentionally crippling Google websites on non-Chromium browsers: given how deliberate such acts of crippling are, I have reasons to believe that it's part of Google's "works with Chrome" strategy, and I'd doubt that Google employees can do much against it.
The only way to fix the governance of Chromium is to effectively chop all the threads that connect it to Google. As long as Chromium developers who are employed at Google won't do anything that goes against the strategy of their employer, you can't have fair governance.
I'll add that whatever the purpose of this project, it isn't going to help the overall openness of the web and will only continue to boost the adoption of an engine that already has an outsized influence over web standards.
