The reason as to why enough people, to make the fact noticable, dont like Medvedeva is that Eteri Tutberidze, being and incredibly ambitious coach, ruthlessly exploits the COP. They hate her the same way people hate Lenin, for ruthlessy exploiting Russia's incredible crisis caused by monarchy, for personal gain. The same way why people hate Stalin, for his ruthless exploitation of the Russian people's blind trust in a firm hand.
I'm obviously not comparing Eteri to either of these two brilliant murderers (despite having Shelepen, Lipa, Pitkeev, Tsurskaya, "stumbling" on her path to success. But the scale and nature of these similarities is to great to make a real comparison). What I'm trying to say is that people dont like the idea of ruthless exploitation... or any exploitation.
A big portion of this hate is transfered toward Medvedeva because she is the one winning medals and setting records, not Eteri. That's basic, faulty, human psychology. Oh, and Medvedeva doesn't get punished for her mistakes exactly due the COP exploitation. There isn't really anything to cling on to. My train of thought is that when your system is getting exploited, change the system. However, when the sport is inherently subjective, doing that is very, very difficult.
I'm not sure that everyone will understand my thoughts, but that is up for discussion.
Happy holidays to everyone and enjoy the Russian National Championship!
