FWIW, while I represented Google in the HTML working group (for a few years; it was a complicated relationship), my work on HTML at Google was primarily done via the WHATWG.

I was not involved with AMP's development at any point that I recall.

Thanks for the response! I had a feeling that AMP came from some other part of Google not too concerned about open standards.
