> While there are definitely many people who would like the latest-greatest OS on their device, I think a large number of people would be happy with their device's current OS, patched to ensure that it's not vulnerable to an active 0-day exploit. most people don't care about patch level either. if they care about OS versions at all, they just want the option to decline so their old phone doesn't get "slower". outside of my tech friends, no one I know takes security updates into account when purchasing a new phone and/or retiring an old one. in any case, OS security updates are only part of the story. eventually important apps you use will require a higher OS version for updates. then you're using a secure OS, but possibly stuck using an old version of an app with its own known vulnerabilities.
