I had a friend with a common Indian name get bounced off a flight and then be unable to book flights after it turned out he shared his name with someone on the no-fly. He had to petition his senator/congress person to get off it. TSA had no easy way to prove innocence. It was very clear the list was just a list of names with no useful or distinguishing unique fields with it.
This was roughly 10 years ago, so things might have changed, but at the time it seemed like federal agencies could easily append to the list, but there was no standard process to get off it. I'd guess there are obvious incentive for agencies to add ("hey look, we've found terrorists", even if nothing was actually done about it), and none to remove people from it.
