Sorry for being skeptical but the impression i have about all of this is that at this point Eteri has such an influence on the federation and media because of the status they gained over the years, you can't freely call her out, and say that they forced you to switch or retire, i bet they are so smart, it's all written in the contract these skaters sign before joining, like an NDA.
Basically those who do criticize the team, are either those skaters who were immediately trashed, so their competitive career is done already, but russian media and supporters are very smart at downplaying everything, making it seem like that skater is just jealous. (which also could be true, but you can't just dismiss the whole thing just because it's not all rainbows and unicorns)
Here in a western country, after an interview like the one Polina Shubodreova did, which had several big claims against the team, there would be immediately investigations against the coaching club, in Russia it always go the opposite, defend the coach, trash the skater for speaking up which i think is unfortunate.
Anastasia Shabotova said that that all Tutberidze students take pills to get consistency, basically entire Russia bashed her, scores at following competitions started to drop significantly and now she competes for Ukraine. Before that comment her career was mostly on par with Anna Frolova btw (who got 2 events in juniors), after she was pulled out of the junior team and forced to switch country in order to compete at international events. Very unfair situation there, yes it could have been just a mistake, but an apology was enough, you can't destroy her career immediately after.
Like i said for Sambo70 skaters i bet it's behind some sort of NDA, though probably put in a shady unfair way since you can praise the team but not criticize it (if it is a real NDA you shouldn't be able to talk about it at all, positive nor negative), or maybe it's just threats and fear put on the athlete.
It's curious that the recent exodus happened while Tutberidze was not in Russia.
