I want whole-ass macOS on the iPad, and not only are they not doing it, they're doing the reverse: massive adoption beyond early apple's technical/creative userbase is leading to the iOS-ification of macOS. Lower level controls are increasingly locked behind padded walls. I'm old enough to remember when the radio button for "allow apps from unidentified developers" was just... there. I didn't need to hunt stackoverflow for wacky CLI workarounds just to install indie software on my own computer.
It's uniquely unfortunate for apple too, because it's apple. Surely bringing desktop computing patterns to finger/pencil interfaces has a lot of hard problems in need of novel solutions, but there was a time when apple was an HCI powerhouse, and would have been as good a candidate as anyone to try and tackle such things. Could ~2013 apple have done windows 8 better than windows 8? In their sleep, IMO.
Anyway, do people have favorite takes on the actual motivations behind this? Does it truly come down to a desire to own the platform e2e and keep raking in that sweet sweet app store tax? Or is there some kind of more nuanced incentive structure at work?
