The issue gets brought back every time takedowns are the deciding factor in scoring a close fight, like Cejudo vs Mighty Mouse. We pretty much all agree that a takedown with just control, no damage, no serious attempts to improve position or submission threat, should never matter more than a knockdown, heavy damage or close submission attempts. But sometimes, just like in Cejudo against MM, there are no big actions, no moments when a fighter is in imminent danger... In that case, such takedowns with only harmless top-control do become the highlight of the round and the decisive scoring factor. Judges aren't actually counting the strikes and rewarding the guy that landed 2 more jabs, or using algorithms to decide if a heavy leg kick is worth more than three weak G'n'P punches. If a round is close within a certain margin of error, the guy that lands the biggest move will get the round, even if the move is not actually that big in itself. This is nothing new or unfair about it.
