What exactly did she do disrespectful at the medal ceremony? I googled and found the clip below and I don't see anything disrespectful. I mean for starters let's be clear 75% or more of her face it covered in a mask. Does she seemed thrilled, no, she looks upset but that's understandable and nothing disrespectful looking based on what I could see, based on what I can see she had been crying and was either trying to not cry on the podium or trying to contain the amount of tears. When I think of a disrespectful medal ceremony I think 1994 Worlds from surya bonaley where she initially refused to get on the podium and while on the podium almost immediately took the medal off her neck. Look at that then look at Averina at the Olympics, not even close to disrespectful in my opinion.
From the very little I know about the Surya Bonaly situation, while I understand how it's perceived as a disrespectful move and unsportswomanship, it's still a different story than with the Averinas. Surya was a top contender for many years, got very rarely rightfully credited for her talent because of her lack of artistry according to the era's standards (and also a touch of latent unconscious racism), truly worked her butt off to improve and give the judges what they wanted, but there was just always a reason to never allow her to be a World champion. This time she was so
, so close, she gave one of the best skates of her life, but still a nope. It was the last straw after too many years, I understand she was pissed as hell and to me her gesture isn't unsportswomanship, it's a political statement. Not the same. But again, just my opinion and I completely see how it's inappropriate in the eyes of many.
Regarding the Averinas, I do not consider myself a RG fan - I know jacksh*t about the rules, only saw a few (terrifying) documentaries (seriously, how is Viner still allowed to take "care" of young girls?!), binge-watched London, Rio and a few other olympic finals, and watched Tokyo's a few days ago. To my untrained eye, Linoy Ashram deserved the win, she showed supreme confidence, grace and power, the ribbon mistake was the only false note in four amazing routines. I felt Arina Averina was a bit underscored, and very unlucky with ribbon, I feel sad for her but at least she can somewhat only blame herself for the 4th place, she seems to have accepted it better than Dina with her silver.
To be honest, I knew about the Averinas only from name and reputation, I never saw them perform before, and I was quite disappointed. Mamun, Kanaeva and Kabaeva felt much more remarkable and unique to me, I truly couldn't really see what was
so amazing about the twins compared to the other competitors

In all of their routines they both seemed off and very nervous to me, though to be fair the more the competition progressed not in the way they wanted the more it seemed to throw them off.
I feel pity for them, Russia's absolute dominance in RG was bound to end at some point, and it happened to them. While the anarchist in me is always happy to see empires fall, it's often the lives of innocent individuals who get crushed in the process and they did not deserve that.
I absolutely do
not approve of the death threats and atrocious hate displayed all over the Internet on Ashram and the judges
(and frankly Zhenya's statements in her interview felt totally off and inappropriate to me - oh and also, could someone take the Internet out of Yagudin's hands please ? ^^'), but at least Russia's frustration isn't being taken onto Dina and Arina for "failing" to live up to the country's golden standards. I guess it's better from them to be remembered as the-girls-who-were-robbed instead of the-girls-who-failed-and-ended-the-country's-reign-of-glory. Imo, they are a little bit of both ; and for the second point, that's okay. It happened to them but it could, and would, have happened to someone else, if not this year then another one. It's hard and painful, they'll have to heal and learn to live with it, and I hope they'll make peace with it. They still have plenty of gold medals and achievements in the sport.
However, I confess I am extremely happy to see this happen to Viner. That's 100% karma backlash,
finally 
As we say in French,
cheh !
