Running an NVMO seems like a massive hassle; if there's no profit in it then there's less of an incentive. And while an Apple NVMO could confine it's support to a very narrow set of hardware there would still be something very un-Apple about the whole thing: inability to CONTROL the physical network on which the NVMO is operating... even more so if, like Google Fi, more than one physical network is involved. I don't know if Google is in the FI business for making money so much as creating an exclusive option for owners of Pixels and a handful of other approved handsets. Apple doesn't seem to have problem selling expensive phones so having a network to manage/coordinate is a headache they really don't need.
