I think you'll need some evidence for that. Silence is not consent, and it's certainly not enthusiastic consent.
And even if you do want to take silence for consent, the fact that the vast majority of millions of millions of web users do not install an extension to route around Google AMP indicates that they do not want the operators of the web page to do whatever they want, they want to run a restricted subset of what the web designer might imagine. AMP is extremely popular among web users; approximately 100% of Google users use it. (The more defensible argument, of course, is that users don't really want AMP, at which point the question of what users really do want gets back on the table.)
Also, users did vote with their feet against downloading EXEs from the internet - which can actually do whatever the developer wants - and using JS on the web platform, which can make unrestricted GET requests (even if it can't see the responses), sure, but can't do anything near "whatever." It stands to reason that users would gladly accept even more restrictions on the execution platform.
