until they publish the technical specs sufficient for community support and repair.
I want to see phones with no further official OS support have their boot loaders opened up so a lightweight OS can be installed on them instead. I've had iPhones in the past that have been absolutely rock solid after a battery replacement that lost iOS support, and with that a whole bunch of resale value. So I now tend to sell mine a year or so before they're likely to be dropped.
But I genuinely think that I'd hold on to an iPhone that could have an alternative OS installed. This is, of course, why none of the major manufacturers allow this. Gotta put the profits ahead of the ethics.
