What about devices that are connected to the internet and need security patches?
As a software engineer can you imagine supporting every version of your software you ever released? Sounds like a nighmare.
This would teach us developers to do better. Like don't push random updates that break shit. If your product is not filled with security issues you should be able to backport a fix for that giant secuiry bug you found, you can ignore the crashes. Anyway this big companies can afford to pay you to backport some fixes . It is not like some volunteer is forced to backport fixes in his free time.
Perhaps we (developers) need to get better at this. We care so much about pushing features and being agile and all, but when it comes to supporting old releases: "umm, no. It's a nightmare".
