Says all you need to know. They are going to shove this down people's throats, whether they like it or not. Maybe not now, but it's coming. It's kind of disgusting how they talk about this change so matter of fact, as if Chrome is the only choice that people have.
No they didn't, why do you lie like that?
And which ones are that? Time to first byte, first content paint, render blocking resources?
For an example, see any discussion on Chrome-only non-standards like hardware APIs where people are convinced they are standards and all other browsers are holding the web back.
Their entire web.dev site is nothing but Chrome propaganda machine that frequently posts about Chrome-only tech or APIs without mentioning they are Chrome-only and possibly never have the chance of becoming cross-browser (web transport comes to mind as a recent example: shipped in Chrome, its status is literally "some ideas scribbled on a napkin")
