IMO the placements are dependent on the scores. When you say the placements are all that matter you give yourself wiggle room for the scores to be off. Scoring can be off for numerous reasons....from the innocent wrong number keyed in, unable to decipher a judges writing to the possibility that scores were actually out of range and not consistent with what was put on the floor in that routine vs the rubric, esp when compared with others in that division. This then opens up major can of worms as to was it intentional or not, who should of really won or moved up if scores were correct, etc. Now add to that the nature of social media now, and you would have screenshots, zoom in's of every team to back up or dispute those results. Which is a PR nightmare, which they may be trying to avoid. (Not saying in this case, just as a general business practice)
My question is if you can't trust the scores to release them, why should we trust the placements? You could just say whomever you wanted to win was the winner and the rest are out of luck. That does not inspire confidence to keep returning to any event or sport. That again makes it not a sport, and makes it something less likely to be supported by the masses as such.
