There was a round table discussion that weighed in a bit on this from Russian skaters' views (Medvedeva, Skoptsova, Averbukh, and Yagudin).

Anastasia Skoptsova: Unfortunately, this is not the most pleasant topic. A video appeared on the network of Maya and Alex Shibutani literally swearing, it's even difficult to call it swearing, because Alex scolds Maya like a little girl. She is standing, silent. It is not known who is behind the board - presumably, this is their mother. He shouts at her loudly, bad words. Long video.
Ilya Averbukh: Wait, are they brother and sister?
Alexei Yagudin: Relatives.
Skoptsova: They interrupted their careers for 7 years. This is not Kamila's two years for you.
Evgenia Medvedeva: After the 2018 Olympic season, we did not even skate in the show for seven years.
Skoptsova: Maya managed to overcome cancer. And now they are back together, they say that they are in great shape, but recently they leaked this video. First of all, a question to, forgive me, the bastards who do this. What happens between the coach and the athlete, between partners in training – in no way should end up on social networks.
This is simply unethical. If I had come across such a video, I would never have posted it.
Averbukh: This is a person who latches on to this topic and promotes it. You contradict yourself. So delicate: I wouldn't blow it up, I'd be in jail... Here, some bastard posted it, and now we will start discussing it in all ears.
Skoptsova: Some guy leaked the video, filmed it on the sly.
Medvedeva: This is a live camera. Someone filmed it from the screen and posted it.
Skoptsova: What am I getting at? What happens between the coach and the athlete, between partners – no one should know about it. It's like going into your kitchen and filming what you and your wife are talking about, swearing, who didn't wash the dishes. <... >
Averbukh: I hope there are no pushes there? Well, that's all... This is in any couple. The partner is standing, shouting, the coach is waiting for them to talk themselves out. An ordinary story. Moreover, they are brother and sister.
Yagudin: And in your pair with Irina Lobacheva, who shouted at whom? Or no one at all?
Averbukh: They shouted, of course. And I shouted, and Ira shouted, and the coach shouted at us. And they dispersed. You can make a whole film about it. People from other sides, but not us, threw covers at each other.
Skoptsova: Grischuk threw skates at Platov, no?
Averbukh: So what? This is a closed internal process of this preparation, of these guys. And you don't need to write your advice there, pay attention to this. The training process takes place. People work beyond their limits, and they are in this process of nervous tension, in a situation of stress. I say this for such a philistine story that suddenly begins to rush to the defense of one or the other.
Imagine that this is a planet where it is better not to approach at all, not to enter. I am sure that if we go to the training of the guys, to other rinks, everywhere there is its own atmosphere that you can snatch, catch and then give your advice.
Medvedeva: Okay, you say it's beyond the pale. Is there a line at all?
Averbukh: The verge, of course, is physical violence. <... >
Skoptsova: Going back to Maya and Alex. There is profanity in the video, but no matter how ugly it is in relation to a woman, to her own sister... Kirill Aleshin and I had a difficult off-season before winning the World Junior Championship, and we argued so that this was just a nice conversation.
I screamed, Kirill freaked out. Judges came to us to watch the programs. When the judges come, everyone rolls and smiles. And we had such a fight that Kirill ran out of the ice. I was afraid that he would take the skates now, and I would never see him again. We shouted not only obscenities, I'm afraid to even say.
That's the kind of sport. And there were cases in history, I will not name names, when the partners of their partners with supports deliberately dropped their partners, and with their heads on the board... True, there were such stories.
It seems to me that what is in the couple should remain in the couple. And what is between the coach and the athlete should also remain between them.
