This is just one of many reasons, but try this on a mobile phone.
Go to Google and search for "Trump"
Note what choices you have to pick from without excessive scrolling. They all end in either ads or Google urls.
Click one of the featured stories in the carousel, almost guaranteed to be an AMP site. Seems to be a prerequisite to sit in the carousel.
Lets say you land on a Washington Post story. What do you think a "right swipe" should do? Should it navigate to a competitor of Wapo? This is Wapo's page, right? So it should go to another Wapo page. Nope, it goes to Fox News.
Okay, so now you've navigated from Wapo to say Fox News. Hit the back button. It should go back to the Wapo story, right? Nope, goes back to Google.
How this isn't viewed as a land grab is a mystery to me.
I googled "Trump". First five stories in carousel (wapo, bbc et all) are not AMP. I see only one AMP link in the first page results. Click on it, page loads. Swipe right/back button gets me to Google results (as expected). Is it because I'm on an iPhone and this is an Android thing?
Same search though ddg with !g comes out completely different though....
It certainly makes it clear that the content owner of an AMP page is not the page owner.
Also, I missed mentioning the [X] button on the AMP header banner. I bet that most end users think that [X] button should make the AMP banner disappear, while leaving the page content there. Pretty common pattern, like for the EU cookie warning. That's not what it does, though.
Back to the "right swipe", at the very least, it should do nothing, assuming that an AMP page belongs to the publisher.
Dark petterns, MS, google, facebook etc. It's becoming the norm for the behemoth corporations to do this.
Well, with AMP, the the mobile results are basically ads, then AMP results which are guaranteed to have Google ads. So the percentage of searches makes Google money increases while similar reducing revenue from competitive ad networks who are not approved.
You mention the [X] button. How many end users do you suppose think that the [X] on the AMP header bar should make the header bar go away...versus functioning like a back button, going all the way back to the google search? I suspect they are conditioned by things like the EU cookie warnings that an [X] on a header bar makes it go away.
An AMP page you reach from a Google search is Google's page, period. It's not the publisher's page. And that's no accident or side effect. It's the whole point. Performance is a secondary concern.
