Opposite of web standards? It's HTTP+HTML+JS+CSS. What part of AMP isn't standards compliant?
It's a classic walled garden, like the Android app store. You can develop Android apps that don't meet their guidelines but you can't distribute them through normal channels.
But I believe the larger issue is how it makes URL meaningless, and futures a centralisation of the web. It's not against the standard, but certainly the spirit of the web as it was supposed to be.
The part that mandates including js from a corporation on your pages.
