On the one side, locking down the Mac even more would be the worst idea Apple could have because this would push even more users out of their system. On the other side, looking back at the past few years, it is quite possible that they do so. The recent changes in both their OS and hardware indicate that they absolutely don't care about their pro users.

Hard to predict which path they choose, but I try to stay positive and assume that they have at least one manager capable of thinking rational and in favor of the pro users.
