I don't think that's realistic, very hard to enforce. It'd be like opening a can of worms, you could have some skater do a twist on something another created and the last thing this sport needs is the bs that would introduce the original skater tried to stake claim to something. Like I don't think what the Russian team did is terrible, clearly inspired by a program they liked. I suppose one could try to argue that for the Chinese team but I see that differently as they didn't borrow, they just took and at best it's incredibly lazy, but I imagine when they did that they didn't expect their performance to be viewed by FSU posters all over the globe. I wonder how often it happens that we never see.
As for Yuri on Ice, didn't Madison Hubbell say recently in an interview they all watched it and laughed at the choreography they lifted from V/M programs. I think Tessa and Scott were there so it would seem they don't mind that. That is probably just fun and flattering for all the skaters they imitate.
