The problem is, there really isn't an "AMP independent of Google", as Google's implementation is the only thing that matters, due to Search and Chrome. Supporting Google's proprietary fork of HTML is more or less supporting that entire structure, and it is inherently harmful. Whilst they have some notion of "governance" for the project, the plurality of participants are Google and they've confirmed that Google isn't really beholden to follow the project's governance with the implementations they put into their own products anyways.
For the most part, AMP is a subset of HTML with proprietary tags, but could be easily implemented in normal HTML. The only reason to implement AMP is to format your website to be compatible with Google's demands for special treatment in Search. (A benefit that, while publishers may aspire for today, becomes increasingly useless as the entire Internet is forced over to the same proprietary format.)
Various blogs have covered samples of how loading AMP is actually worse than loading their own websites in a lot of cases, but they're forced to implement it anyways because of that Google Search incentive. Surely the correct solution for mobile developers is to teach people to use restraint in piling on extra crud, not bootstrap some extra crud that prevents them from using any other crud.
And essentially, from the responses here and in almost every previous discussion about AMP, and literally Twitter feeds made just to retweet examples of AMP hatred: Nobody wants this. Everyone who wants it is using it because they have no choice. It's forced on publishers to maintain competitiveness in search, and it's forced on users who have no way to decline.
Probably what ground my gears the most about your blog, to be honest, is the cheerful, supportive tone for what is inherently a harmful technology that was implemented in a closed fashion. Compare to how FastMail acknowledged that they may have to support AMP for Email, whom I'm not upset with: https://fastmail.blog/2018/02/14/email-is-your-electronic-me...
If you have to do this for business reasons, tell us that, don't try and tell us AMP is good for the world, when we know it isn't.
