There is having Control and needing it to exist. How do you feel about the second? Is he making and following these choices up to your standards.

Is speaking up hard? If it is I would suggest there is something far deeper that is the issue at hand.

Another thought I will throw out here... it must be hard (and frankly I find questionable) to have that close a relationship with his parents. Consider what kind of control they have over him. Is it possible then that this is his way of trying to extert some control when so much of it is missing in his life. Maybe even this is his subconscious way of rebelling against that.
