Lol. I don't remember the last time I came across an AMP page that wasn't missing content.
There's exceptions like restaurant menus at specific places that I'm considering, but certainly there's no mainstream news article that's worth me staining my eyes over: if it loads a desktop site on my mobile phone I'll definitely just hit back and move on regardless of the content.
I constantly find myself closing pages on mobile within the first second if they're taking too long to render or if they become fucked up from all the ads and comments and social media button, each one dislocating other elements and moving them around as it renders, or just because they were poorly designed for mobile.
There's a huge chunk of content I never bother to see because it's too much of a pain in the ass to actually read on my phone. If I have to adjust the zoom or scroll to a different part of the page to see any text, you've probably already lost me, unless it's content I went out of my way to seek out.
