Does Google have any plans to let users opt out? Maybe an icon that takes you to the original? I tried opening the AMP link in a new tab and it took me to the site, so at least there's a workaround.

Since I normally use Firefox Mobile (has to try it with Chrome), I don't get the AMP icon and I'm taken to the requested site. I'm guessing this functionality is limited to Chrome and (maybe?) Safari on mobile.

AMP is attempting to solving a challenging problem, and although I don't personally agree with their solution, I've gotta recognize that opening the embedded AMP version of the page from the result of "git tips" was faster on Chrome than on Firefox. I'm hopeful that the lessons learned from this will be pushed upstream and help improve the web.
