Walled gardens and proprietary software can allow for fantastic user experiences in a way that open platforms often cannot match. However, I feel focusing on the user experience misses the main point - the web is an open platform, and this is an example of Google exerting an authority that many may not feel comfortable with.

In what way is "indicate that this website is slow" a walled garden or contrary to openness?

Because the criteria will inevitably be biased towards technology and techniques that favor Google, Chrome, AMP, etc. If you trust Google to be an unbiased arbiter of objective measurements of website efficiency, you are giving them a lot more credit than I would at this point.

Visit an AMP page in Lighthouse and you won't see an especially good score. Lighthouse doesn't special-case AMP or pick metrics that would make AMP look good.

Just because a monopoly is not acting maliciously today, that doesn't mean that it won't tomorrow.

In the United States, the role of a central bank is to manage two measures: inflation and unemployment.

The US Federal Reserve Bank does not measure inflation or unemployment. Rather, the US Department of Labour, an independent organisation (and a branch of government rather than a freestanding entity) computes both measures.

This is the principle of division of responsibility and measurement or judgement. You cut, I choose.

Google are both measuring, and rewarding, website performance, as well as designing and distributing the principle tools that benefit by both choices. That's an extreme locus of power. And, history shows, generally a Bad Idea which Ends Poorly.

Also given their market share as a search engine, they also get to decide which websites you will be able to "discover" additionally incorporating their performance metrics into their website ranking. So not only a website will get a "slow badge" but will also be downranked into oblivion.

Because Google is the decider of what constitutes "slow"? You have a single organization deciding what the threshold is between slow and fast. And, they also have a Google-approved solution (amp) that I'm sure they will tie into the recommended actions for "slow" pages.

I'm not saying it's a walled garden (that's a more extreme situation on the continuum between open and closed), I was just using the phrase to illustrate my point that the end-user experience isn't the only factor to consider.

If Google didn't have a long history of this sort of thing (interpret that as you may) the open web would have lost the battle for mainstream users to the proprietary platforms long ago.

I don't love using slippery slope arguments, but I feel that it's appropriate here...
