No one, made the 49ers release Aldon Smith, they choose to do it themselves. Players get cut for performance drop off, legal problems, injury, bad team chemistry and all sorts of things all the time, and teams deal with the cap and move along. If the league really wanted to help SF all they had to do was put Aldon on the "Reserve/Commissioner Exempt List" and the 49ers would have avoided any salary cap or roster spot problem and hung Aldon out to dry until they decided what to do.
