So which devices actually support LineageOS, though? The one that wipes its proprietary firmware for the camera, leaving you with one that is orders of magnitude worse than the day you bought it?
This may not matter as much for a tablet, but let’s not give the impression as if the android side of things were better. Especially that that ipad will have insane lifetime. That android tablet may not in the first place.
Totally not true, I am at my second "out of support" device on which I install LineageOS and enjoy current Android. Just unlock the bootloader.
If you are tired of Apple selling basically hardware-as-a-service with strong planned obsolescence, don't buy their products, problem solved.
