Ah yes, Microsoft’s “we care…………to talk about problems we’ll never fix” poster boy. Dude might be a fantastic developer, but he’s being used as a sock puppet.
Especially in the last few years, preservation has been a big topic. Gamers want their purchases to keep working in the future, not being broken by an OS update as it often happens with macOS (compared to Windows)
A lot of game industry operates on a "release and move on" model; nobody has time to keep updating an old game hardly anyone buys instead of working on a new thing. On PC and console this is fine because your games keep working more or less indefinitely.
But the vast majority of the games I've purchased on iOS can't be installed anymore. It's not great. In some cases the games still function, but I can't download them on new devices because the developer closed shop and disabled their Apple account.
