You are absolutely correct but it will never happen. The NBA views criticism of the officiating as a direct attack on the integrity of the game (as if them pretending like everything is normal when calls like in the DAL/GS game are made is not damaging).

The NBA HAS to have the appearance of impartiality and fairness or else it is the WWE. If fans are bitching they can just say that fans don't know the game well enough to make those accusations.... but when players and coaches are saying it, all they can do is say "shhhhhh!" and make it costly for those that do not keep in line.
