Apple provided 5 years of full years of updates. 2016 through 2021. I understand the writer’s issue. It seems clear some amount of support should be mandated. After all no one should be able to drop support after 1 year. But what is the correct length to mandate? Until the radio standard is no longer usable (so when 4G gets turned off)? Just a specific number (5, 7, 10, whatever)? I can’t think of a single consumer device that has mandated support for any length of time past the warranty, so I don’t think there is precedent. In fact the only mandatory support I can even think of is parts for cars. So how do you choose the timeframe?
