Long story short, I don't see it as best practices that serve Internet users as a whole. They seem to be more closely tailored to the interests of Google. And, by extension, the subset of netizens from which they can generate the most revenue.
Do agree that the proliferation of acronyms doesn't help with wrapping your head around it all!
So, yeah, Google may want to encourage a nice Web experience, but they don't want to back this with metrics that might discourage people from sending too much business in AdSense's direction, or fail to favor Chrome over alternative browsers.
Your Core Web Vitals report in Search Console is based on Chrome User Experience Report data. Meaning that this is data from your real users, not Google running simulated tests of your pages on their own servers. I.e. when someone loads your page from Chrome, Chrome reports back how long it actually took the page to load for that user (it doesn't happen with all users, they have to meet various opt-in criteria [1]). So, if you see that 50% of pages are served too slowly on computers, it means that 50% of your real users actually experienced slow page loads (as measured by the Web Vitals metrics). Perhaps your static site isn't as efficient as you think, or your server is slow, or the devices/connection of your users is much worse than you assumed. That's the power of this data; it shows you that in the real-world the experience isn't as great as you're assuming and encourages you to investigate further.
(For the record) The landing page of the Core Web Vitals report does indicate where the data is coming from. Next to "Source: Chrome UX report" you see a question mark. If you hover over that question mark then click the "Learn more" link it takes you to this page: https://support.google.com/webmasters/answer/9205520?ref_top...

At least they link to a lot of docs and advices.
Also funnily enough they complain about Google Analytics.
Both of those metrics account for the visual completion of the page relative to its final appearance -- deferred resources would slow that.
And, as I read in the article, it looks like behind this move there is some current "Antitrust Pressure" plus publishers quite pissed off about losing both control and revenue themselves (as much as 39% less conversions, they says.).
Clearly AMP was way more in Google master plans than a poor web performance palliative.
[Edit]
This was the article linked to this story when I commented (now changed to some Google Dev docs):

It was open source, it was used by many others including competitors, it was optional and it didn't block access from anyone. Having an AMP version in no way "locked" you to any garden, AMP versions aren't even meant to be the canonical page anyways.
It may have had a lot of issues, but "walled garden" would not be one of them.
And it was as optional as publishers were almost forced to jump in it to stay relevant in News SEO.
This "Google was just forcing publishers to fix their pages" meme desperately needs to die. Just consider all the extra standards crap they were pushing to introduce to perfect the deception. This was, as always, about owning the data.
Google doesn't need to own the data because Google is the world's gateway to the open web. They don't care who owns the data as long as they can crawl it.
My only complaint is the smirky, chipper PR front they package with it. Microsoft, at least, wasn't too insecure to show some fang without the Candyland faux-earnest horse shit when they were king.
And I say this as someone that thinks that Google is the scariest company out there, right now.
It's absolutely Google’s job to decide what quality signals to incorporate into their search rankings.
Google is also at a scale where they can improve the quality of everyone's web experience with their scale. It' not so much "their job" as "their obligation."
In that sense, their approach is in some way more equitable than Microsoft's: they're not forcing change upon your system by way of mandatory updates, they're simply saying that if you don't play the same game they play, they're unwilling to do business with you.
If you're free to maintain your server to your standards, why should they not be free to maintain their search service to their standards?
Speed is valuable because it allows users to more quickly digest whether the result is relevant to them.
And then they plug that computer into a global multi-user network and their machine is botnetted and used to harm other users. In that context, people are no longer making simple decisions and accepting the consequences; a tragedy of the commons is instead created.
Your thinking works when computers are isolated from each other. When they're not, it's in the same category as "states require annual vehicle inspections." Because when you're sharing the road with other drivers, you owe it to them that your vehicle is unlikely to undergo catastrophic rapid disassembly.

The second recipe result is Betty Crocker and as you’d expect — recipe at top, steps with photos after.
I personally find more of the former than the latter when looking for specific recipes (Red wine chocolate cake was my most recent search)
They would indeed prefer to be utterly ignored by designers over being gamed to but SEO remains something optimized for like clickbait titles and headlines.
