At some point Ive became to have major role in making decisions of what's going in to production. Jobs had serious health issues, couldn't keep his eye on everything and finally he passed away which made Jony the guy who was making decisions pretty much on his own. I bet that trashcan MacPro, butterfly keyboards, "thinness war", sticking for too long to one design etc., those are all his ideas that he pushed trough.
Quite recently Apple realized that leaving everything in Ives hands is not that good idea after all and I have a feeling that redesigned MacPro and decision to ditch butterfly keyboards from newest MBPs was forced on Ive and that's the real reason behind him becoming external contractor for Apple. They couldn't fire him completely but they needed changes and Jony didn't liked restrictions on his design choices so they've split.
As for the future, we already saw that story in the past and as we know history like to repeat itself. In the next 2-3 years Apple products will become more in line of what users wants. They finally started to listen to people and it will result with better products, at least in short term. Times has changed and I hope that history will not repeat itself in the next step when, like in the 90s, Apple will become shadow of it's former self, trying to build products based on financial statistics and polls and not on engineering and design talent of their employees. After all we think we know what we want but in reality there will be products and solutions that we can't imagine right know and no amount of polls will give the answer to a question what's next, what's behind the horizon.
