One other aspect about AMP, particularly as it refers to Google Scholar. Publishers get paid based on COUNTER reports and if you’re driving all the abstract traffic to AMP pages then their page views registered by COUNTER (an industry standard) are not counted, and hence makes the publication very attractive to librarians to cancel (as the vast majority of views are to abstract pages). Google has been working on linking that traffic to the publishers web site but it again is decreasing the publishers brand to highlight google’s, and that’s why it won’t work. (Views are my own and not of my employer).
