The interesting thing about this to me is that they’re doing it in solidarity with Trump and to draw attention to the assassination attempt, but 1) he wasn’t really injured significantly, 2) the assassination attempt seems to not have had a political motive. So, there’s not much to show solidarity for, and there’s no enemy they’re calling out.
That isn’t really how the judging worked though. First they had a huge panel of judges - 9 of them. And they judge them on 5 criteria: technique, vocabulary, execution, musicality, and originality. It is qualitative, but it’s a comparative rating system with actual guidelines - so they each simply have to decide who did each thing better:
I don’t think breaking necessarily needs to be in the olympics, but we’re past the point of only allowing sports (looking at you, dressage) and we do have other artistic events (rhythmic gymanstics and synchro swimming). And, the scoring system for breaking was reasonable and able to determine valid winners.
