It's also interesting that Windows Phone -- I'm intentionally using the term very loosely -- showed that it's possible to offer lower-end devices that do receive security updates straight from the OS-maker on carrier networks, although a myriad factors, including hard reboots of major versions dead-ending entire device lines, and a less-than-thriving third-party app ecosystem due to another set of problems doomed the entire ecosystem in the end. But Microsoft mandated UEFI to rationalize the clusterfuck that is the "ARM platform" from the very beginning, and made it so that the carrier would have to explicitly disable an MS-pushed update, rather than the Android equivalent of the carrier having to prep the update in the first place.
