Can’t Google do manual penalties for some sites? How hard would it be for them to do manual bonuses for the top 100 sites in the world. That would be pretty much equivalent to domain authority, and I expect Google is doing just that.

Google penalizing an amazon domain would likely trigger some kind of legal action?

Probably, but I’m suggesting they are doing the opposite, and that therefore domain authority does indeed exist.
