I agree and I think the reason may be that some people are associating this "total control" director idea with George Lucas.
George Lucas is one of a kind he had total contol over the Star Wars films before he sold it to Disney this is partly why Hollywood hated him.
No production company execs to tell him what to do or even have a say in what he did good or bad.
He wrote the stories, produced, directed and had the final say on everthing even on the films he didn't direct, because he owned the rights to the films.
This will not be the case with Abrams or any other director.
Good Point! also, Lucas was hated because at the time of EP. 4 (1977) Movie credits were shown at the start of a movie, Lucas put them at the end.... A trend he started and now followed by many.
