> Apple and Google don’t value backwards compatibility that much
I'm incredibly disappointed that something like 40% of the many apps and games I've purchased for iOS no longer work.
The 32-bit apocalypse was terrible, but Apple's contempt for ABI stability and backward compatibility in general (resulting in an ongoing compatibility maintenance burden for developers, just to keep their app running on newer iOS versions) damages the app and game experience on iOS.
Apple's approach makes it impossible to build a game library the way one can on other systems without keeping a collection of devices that run the appropriate OS versions and have the game installed (since it may be removed from the app store.)
This is very different from, say, Nintendo DS games(2004-2020) or PS1 games (1994-2017.) Or PC games on Windows and Steam.
It's a disappointing tradeoff, because better backward compatibility would have massive, multiplicative benefit to iOS users and developers.
