All of this reinforces my point, which is that Mozilla is not simply following marching orders handed down by "the Google overlords".

Firefox did not take very long to support AVIF (another recent image format clearly favoured by Google). Please do correct me if I’m wrong, but I’m not aware of Mozilla expressing any reluctance over AVIF’s abysmal lossless performance or other shortcomings (some of which have been addressed since), or insisting on using a memory-safe decoder like they have for JPEG XL. Why the stark difference in treatment?
We may not be able to say for certain, but Google’s massive influence is by far the most plausible explanation I can think of. And if the first step in your decision making is looking at what Google is doing, then ‘following marching orders’ is suddenly not such a bad description. (One can argue that with 3 % market share they don’t have much choice, but that’s beside the point.)
Mozilla was a founding member of the Alliance for Open Media, having sponsored Xiph to create Daala, which was later polymerized with Google's VP10 to create AV1. Mozilla has a vested interested in pushing all things related to AV1, including AVIF. That has nothing to do with Google's favor and everything to do with Mozilla's favor. Their hope was to use the existence of AVIF as leverage to give hardware vendors more incentive to provide hardware support for AV1.

Why? AV1 was developed as a video codec. That doesn’t imply it’s as good of an image format nor that everyone who supported its development has vested interest in making it into one. Just because someone has made a cool hammer doesn’t imply they now need to view everything as nails. (This provenance even brings some drawbacks with it, yet this time seemingly no one took a pause before tossing in yet another image format.)

This is the first time I’m reading about this and I’m having a hard time seeing how decoding images would make for a significant incentive to provide hardware support (especially when everyone was already more or less on board with AV1 as a video codec). But I could be wrong, of course. If you can provide any links where Mozilla gives this reason for adopting AVIF or any hardware vendor gives significant consideration to decoding AVIF in hardware, it would be much appreciated.
[2] was anticipatory obedience from Mozilla. Good for them that they grew a spine later (or more likely: they knew that Google will implement it some time later, so the change of opinion cost them nothing).
This is mental gymnastics. If Mozilla were following Google's orders we would not need to resort to phrases like "anticipatory obedience" to describe a neutral non-position; if they were following Google's orders, they would have simply endorsed it, end of story, and then they would have revoked that endorsement in lockstep with Google as well, which they didn't.
Again, when exactly has Google endorsed JPEG XL? When did they promise to ship it in Chrome stable? Sure, they had it in development as an experimental feature at first, but so did Firefox.
The way I read it, both companies were tentatively interested until Google said they changed their mind, and shortly after Mozilla decided they didn’t really care. Correlation doesn’t imply causality, but their positions followed a somewhat similar trajectory at the very least. (In contrast with, say, Apple.)
I just don’t see where you keep getting the idea that Google was at some point far more supportive of JPEG XL adoption than Mozilla was.
