I couldn't agree more that AMP is terrible. I do everything I can to avoid it. Using DuckDuckGo certainly helps, but I will still occasionally stumble on an AMP site. I've created a hosts block list to help me avoid AMP as much as possible. It currently has 3,569 unique domains (works great with a PiHole!). I'm really concerned about Chrome's 'signed exchanges' where they can fake the URL completely. I hope Firefox will never support it.
