Dylan also gives credit where it is due. I seem to remember Martin Carthy being mentioned on of Dylan's album after Dylan "borrowed" Lord Franklin from Carthy. The folk process at work is what you are seeing - not stealing.

Of all the "folksingers" from his era, he is one of the few that continues to perform traditional music in concert - something he doesn't have to do given his body of work.

Dylan is what Dylan wants to be.   He doesn't try to live up to someone elses image anymore.
