My iPad is pretty naggy to install updates, moreso than my Pixel phone even. iOS doesn't automatically update like Android does, but if anything that seems less like it's because Apple disagrees with that and more because their update system is so shit they can't get away with it. It's inexcusably slow to apply updates.

They are the only ones to have lost a lawsuit for doing literally this. Batterygate wasn't that long ago, surely you didn't forget about it already? Heck class actions about it are still happening in various countries!
