Yes, I mean, AMP isn't the solution I might build independently. But, it is built on standard, open web platform features. You can render an AMP article from any source in a manner of your choosing, using the features available in a web browser.

They have started doing this as well, I believe, by rewarding sites that are optimized for mobile devices.

There is a land grab taking place, whether AMP exists or not. The territory at stake is the growing mindshare of users who browse published content (sometimes exclusively) on mobile devices. I would personally love to see a more open movement than AMP or Facebook Instant Articles participating, but I would take AMP over Instant Articles without much consideration.
