Eh not sure if i agree entirely.
They did accept 3 Eteri skaters to sweep the podium at RN but at the same time they were very against the idea of sending 2 Mishin skaters from the same discipline to Worlds.
It all comes down to that list of people who vote for these decisions and if you look at where they come from, most of them are from Moscow and work there, and each of them protect their groups like for example we know Elena Tchaikovskaya is more pro Eteri, while Tarasova is pro Buyanova,... The only two from that group they'd support Mishin skaters are probably Tamara Moskvina and Oleg Vasilijev.
Konstantinova and to some extent Chebotareva's group is probably the only exception of skaters from SPB who are getting some recognition even from muscovites.
That was nationals, not Worlds or Euros teams.
Also, those were juniors who were not competing for team spots.
