I bet "traffic" here means clicks counted by AdSense, so you still have to pay for a click even if the user never really visited your website ;)
In any case, google is just trying to copy Facebook Instant Articles here. They want people to stay within the walls, because they realized they make more money that way.
what is the market share of adwords things (my understanding this is mostly going to be people offering services) that is impacted by AMP? An ecommerce site won't support AMP so won't be affected, and are news sites and blogs going to be using adwords to advertise their news and blog offerings that much?
E: (and then does it even matter if you're ads are still shown on your AMPed site so you get paid per hit?)
