That's not my point. My point is that people were complaining about this not working, and used the scenerio that if developer dies then once the cert expires the app will stop working.
I was pointing out if the developer or company walks away from the app (or dies), then that app may very well stop working due to other circumstances like OS updates. Some people were arguing about how the cert will prevent their apps from working if the developer dies, and I was merely pointing out that if the developer dies, then the app may stop working for a variety of reasons and to complain about the cert seems odd
Yes, OS update is known risk for old apps. That's why people still use Windows 95, Windows 3.1 & DOS for old apps. But introduction of this new requirement for up-to date dev certificate benefits nobody and only increase Apple's control of their eco systems. Some people may like that - you getting safer environment, but sacrifice freedom. You only allowed to do what Apple wants you to do and only in a way how Apple wants you to do it. Luckily we have a free choice of OS (yet).
