The Fire devices seem like they are on life support from a technical point of view (even if Amazon is making money from them). Their fork is really out of date.

Also Meta Horizon OS is based on AOSP. This will probably also affect their development.

Why would a second company freeloading kernel and services from Google change Google's OSdev roadmap? Google could just say to Meta 'fine, fork and maintain it yourself, you're a grown-up company' and continue on with whatever nefarious rug-pull closed source pivot to Fuschia gambit that they might be plotting.

I doubt at this point corps are not looking at that option. But then I don’t know what kind of contract these corps have with Google. I have worked at Samsung and they are such a large incompetent but aware software clusterfuck that they would rather want an almost readymade OS on which they will smear paint and sell. Can’t speak of other OEMs.
