Let me put this another way: if you want to manually kick off app updates, you literally have to see ads. App Store > Today tab (the default view) has ads. Then you hit your profile button to escape the ad center and there is your app update interface.

This has been normalized by basically all commercial OS platforms, but imagine how insanely negatively received it would be if apt upgrade or brew upgrade displayed ads before your packages downloaded.

Apple even shows ads for stuff like Apple Music/TV+/Fitness/News+ free trials in the settings pane.

And people give Microsoft shit for having ads in their platform...at least they don't show you ads in Windows Update!
