I might have conflated disabling with removing.
It might be true that Google disables ME (but doesn’t remove it), but I have yet to see documentation that shows this. This is why I also find your quoted point less-than-accurate.
Edit: I meant to say that it’s not clear whether Google disables ME. One surefire way to confirm this is if Coreboot installation wipes/disables ME, which is why I’ve been repeating this point. Sorry for the lack of clarity.
