To be clear, this is referring to the client side--that is, from the perspective of mobile web searchers, you can't ask Google to hide AMP results from the results page.

To my knowledge, publishers still have to opt into participating in Google AMP, and I assume they can opt out? That was my fear in reading the headline--that publisher participation in AMP is irrevocable, which would be bad.

If you stop doing AMP, won't all of the non-canonical/duplicated/evil amp.google.com URLs users have now shared and linked to your content going to break, meaning that once you go AMP you are effectively trapped?

Good question. I don't know.

Or maybe, once Google has a hosted copy of an AMP page, it will never remove it.
