Apple chose to not allow sideloading or other app stores, again, as a feature.

Ok, so maybe some cars decide not to offer seatbelts as a feature. Oh wait, they can’t, because that’s dumb.

Not having a feature that helps consumers is not a feature. When Apple prevents people from repairing their phones, that’s not a feature. When they prevent consumers from loading their own apps on their own device that they bought, that’s not a feature! It’s comically anti-competitive and bad for everyone.
