The anger about this is puzzling. Is the reasonable logical conclusion really that Apple did this just because they want to oppress its users?
I'm going to give Apple the benefit of the doubt here. I think their goal was to make a stylus a supplementary tool, not a necessary one. I suspect that they became worried that apps would come out with interfaces designed to be used with a Pencil, but making it less than optimal for use with a finger. In fact, I'll bet they were seeing this in some apps being submitted.
Thus, perhaps for now, they decided to remove it completely even for themselves, so that app developers wouldn't be able to do this. My guess is that they will implement it later when they can find a way that prevents compromising the experience of users without a stylus.
Seems to me a type of oppression of its users, no?
