On the one hand I agree with you: on the other I quite like the fact that relatively large bodies of code I wrote 12 years ago still run unmodified (albeit in Windows desktop apps that have received updates and enhancements since then).

Due to these updates I don't know that they would still run on Windows XP but it's nice that the code hasn't needed to change.

Much of the code needs nothing more than a recompile. It’s just no one is doing that.

To run 32 bit stuff you need copies of all the system libraries. You lose a lot of RAM to that. You have to continue to ensure they don’t have bugs. All for apps that are abandoned.

I totally understand what apple is doing. I bet you a ton of those apps were never updated for iPhone 6 screen shizes either.

You would only lose the RAM and the disk space if the 32bit support is actually needed and installed. What’s better - having unused RAM and your app refusing to launch, or using RAM to run your important legacy app?

Oh, for sure - iOS is a different world from Windows though, and it's annoying when apps are left to rot. Does make me think twice about which apps to invest in nowadays though.
