My complaint is that the idea that the decent drawing experience that we have now was part of Apple's master plan for the iPad is incorrect. They resisted it purposely because the iPad was never meant to be a creative device. The issue wasn't limited to visual art; people who wanted to use iPads for its other major creative application - as a music controller - had to use a number of hacks to break it out of the Garageband ghetto.
The core issue is the hobbling of promising hardware because it doesn't fit the platform owner's vision.
I agree that early third-party styli were a pain - I used various Jot versions, which were better than nothing but not great.
But the Apple pencil + Procreate is actually great, and a fulfillment of the iPad's original promise in the drawing space.
