The problem is that you try to put all issues in one slot, when it's not like that, not all of you mentioned is because of Tutberidze skaters, some are, but you know rules are made based on competitions based on what skaters do, the direction ISU thinks is best for this sport.
It's not that the wake up tomorrow and decide that lutzes and flips are worth the same, there is always a reason behind which comes from precedents set by the skaters.
Re-read the post cause it's not about having power but more about challenging ISU rules, exposing flaws in a rule to the point ISU has to change it.
With the quads, they wanted to show that it's a system, girls at that age following that training can land quads, so ISU should allow it in the short because you'll see more skaters landing quads. Yes they cannot propose it directly to ISU, but they can keep showing it in competition and talk about it in state funded documentaries and interviews and complain about the rules, then wait until RusFed backs them up as they are doing now.

With the 3-3-3 i think it was no different, they tried to show it in front of audience and judges and rivals constantly to show girls can land these elements consistently and audience want to see them, and then even tried in competition.
