AMP isn't "run openly" because everything key to Google's business is non-negotiable, and at the end of the day, Google will do what Google wants. This is what I found out when a few of us tried to talk about AMP4Email, where before threatening us with the code of conduct (for bringing up valid security concerns), Malte Ubl admitted that AMP4Email would be implemented however the Gmail team wanted to implement it, and that no amount of community concerns on the GitHub were going to have any say in the matter.
The reality is the "open governance" AMP spec means nothing, because as a monopoly, the only AMP cache which actually matters is Google's. And it's implementation is Google's proprietary business, not part of what they allegedly allow open governance of.
Oh god I'd forgotten about AMP4Email. It's such a blindingly obvious bad idea, and the GitHub response was overwhelmingly negative. They do not care at all.
