Publishers are still able to track pageviews and serve ads, so I don't get what the hullaballoo is all about here.
There's nothing in the AMP spec that stops links from working.
I just searched for "Is Google AMP a good thing" on my mobile, and got the OP's post as the first result (probably personalized?). Had to go to the fourth result for something with AMP, from CIO.com. The page loaded instantly, was able to scroll without things jumping around, and the header link to the CIO.com homepage worked as expected. They were still able to serve ads and count my pageview too, even if I never directly contacted their server.
I just don't get what the big deal is.
