I still think that this discussion is exaggerated.
Mishin made a statement on Mao's 3A, saying it was an "illusion". And I guess that he doesn't like her take-off. So from Mishin's viewpoint, it isn't executed as it is supposed to be executed. He wouldn't teach his students to execute a 3A that way. That's his opinion and the tech panels will have a different opinion, because (I hope I remember correctly) Mao always got credit for her 3A when the landing was clean. And Elizaveta might have the more reliable technique, but we'll see that next season. But this whole article is too short. A good interviewer would've asked further.
And I'll also enjoy watching both ladies doing a 3A next season.
TBH, i recall Mishing implying in an interview that many people do the axel wrong:

"– Да. Могу открыть секрет: многие люди точат коньки, стараясь сделать их как можно острее. А острое лезвие невозможно повернуть в момент захода на тройной аксель таким образом, чтобы создать нужное направление вращения. И прыжка не будет, как бы человек ни старался. Конек должен быть заточен таким образом, чтобы он мог как бы "забуксовать" – именно это создает вращательный момент, который фигуристу остается только подхватить. Если же этого не происходит, прыжок сразу начинает требовать огромного количества "физики". При мужской силе с этим еще можно справиться, при женской – крайне трудно."
Basically: many people get their blades too sharp, and you cannot turn a sharp blade the right way to create right rotation movement when entering a 3A. [...] Else the jump requires lots of physical strength - guys can be strong enough to bruteforce it, but its extremely complicated for a woman.
And this looks like a case of flawed axel technique that judges will not account for as there is nothing really "wrong" such as UR
