AMP is an opt-in thing that publishers have to implement. If you go out of your way to get google to display your AMP content, it's hardly "rude", nor is google "pulling something" on the sites.
A valid critique is that publishers might feel forced to offer AMP whether they want to or not in order to still get traffic and pagerank, but even then, it's not like they're being tricked. It's still opt in.
