Yes it's true that they forced AMP despite some people not wanting it (and I think you are greatly overestimating the fraction of customers that actually care about this either way). But you know what they say, ask customers what they want and they'll say a faster horse. I don't think there's anything wrong or immoral about going against the current wishes of your customers to further the long term wishes of your customers instead.
That is much different than saying that Google is using AMP to make it easier to control results which was what the parent seemed to be implying. If this discussion is really not about AMP at all, but just about Google flexing their monopoly to do things customers don't want, then why is AMP the technology getting criticized for it? Why weren't we criticizing using SSL everywhere when Google depriortitzed non-SSL results?
It literally means a person who purchases something.
No sane person on the planet would consider a person using a search engine for free, "the customer". The customer is the person who buys something - in Google's case, advertising.
