I felt literally forced to leave Google on mobile by AMP. DDG's results are often worse and I end up having to !g, and it's always a punch in the stomach having to see two screens worth of poorly marked ad-results, SEO spam and AMP - all of those getting worse every month. And even then, their indexing of sites like Stack Overflow, Reddit, and other major players with good content is still miles ahead than DDG when I'm trying to find the solution to a problem.

But AMP can pop up in unexpected places, for example Twitter links on mobile used to be AMP until recently. Just changing search engine will not prevent AMP completely
