On the other hand, I can put an open OS on my Android and get security updates long after the manufacturer has abandoned it. Can't do that with an iPhone. (But honestly, few Android devices make it easy, and none that I know of allow every little part of the system to be supported this way.)
It's about time we started legally requiring manufacturers to unlock our hardware when support ends, and release the driver specs ahead of time, so the open software community can take over support. The unending accumulation of e-waste due to nothing more than abandoned software is unforgivable.
