Speaking only and solely for just myself, I do not care whose site I read the material on. I just want it presented in a reasonable, readable manner. A number of publishers seem to struggle with this.
Are your concerns addressed sufficiently?
AMP is opt-in on the publisher's end. Publishers choose if you get their site or AMP.
I wonder what the EU will thought of that.
However it also made Google useless. I may see an interesting page, but then notice that it had the AMP stamp, and no (visible) way to get the non-AMP page.
AMP made Google useless for me. Then I discovered DDG. And now I use DDG as the default search everywhere, because I get more relevant results than with Google! So I guess I should thank Google for ruining their search with AMP and opening my eyes to alternatives.
