So a ton of the stuff that HN folks demand (being able to do dynamic third party javacript ads and tracker loads, DOM modification after render - gone - you just are totally blocked.
If you try targeting AMP (or just consuming AMP) you'll pretty quickly get what they are going for.
For example - AMP websites really do not reflow that often (or at all). I've never I don't think had something move when I was going to click it even early in page load.
I've found a lot of complaints about AMP are developed / hacker focused complaints. If you switch your mindset to users, including non-tech types, the value becomes more obvious.
