This discussion comes down to two things: Whether you think that Plushenko shouldn't be able to advertise his new rink and whether you think that Plushenko shouldn't be able to coach whoever he wants just because he's new in the arena.
I think that as a coach, he has every right to approach other skaters and inform them of opportunities. This is what Eteri did to Zhenya to get her to return, and yet this action was not seen as her poaching Zhenya from Orser. And someone on here will say "but Zhenya needed a better training environment". But why did Aliona and Sasha leave if not for the same thing? Plushenko never offered, as far as we're aware, money or sponsorships in exchange for the skaters transferring to them. Sasha, for example, already has an adidas sponsorship. So his claim about not luring skaters away with contracts is completely true. That should be the end of it. I really don't care if he offered his training facilities to Alina. You think that coaches do not want to train top talent?
The second is that Plushenko is somehow doing a disservice by trying to gain a reputation off of "established" skaters as opposed to ones he's made. Well he has only had three years, and he didn't even have a properly sized rink until very recently. So it is impossible for us to declare he has failed in development when there isn't even the time span for him to develop anyone. In the time being, it is not his job to refuse all talents who want to join him just because he isn't "proven". Aliona and Sasha are two of the best figure skaters in the world. They have their options. They chose him. Neither were conscripted, nor forced. It was THEIR choice. To make it as if they were simply stolen removes all agency from them, takes away their agency in deciding what the best training environment is for them, and allows everyone to conveniently ignore that, while a GREAT coach no doubt, Tutberidze's training camp has faults.
The fact that this is even an issue for discussion is ridiculous, and it should be ended. Neither camp is perfect, but at the end of the day, it is not up to them to be unflawed humans it is up to them to provide appropriate training conditions for their athletes. And it is up to us as fans to support athletes who advocate for themselves and to give them the agency to make the decisions that are best for them REGARDLESS of our opinions of who they're coached by.
