I do not know how true the Valieva doping allegations are. But the West has a habit of smearing Russia and China, and then handing out unjust punishments. So I'm willing to believe that Valieva is innocent until proven guilty.
More evidence Valieva is being smeared by Westerners
Both Valieva and Zhu Yi have been on the receiving end of some really bad press from the West and their minions.
This dumb article by the Guardian blames the controversies of Valieva and Zhu Yi on their respective countries. Russia, for doping Valieva, and China, for bullying Zhu Yi.
Both Russian and Chinese athletes have been unjustly targeted by the Western media, and their names have been somewhat tarnished. Russian athletes are accused of doping. While Chinese athletes are accused of becoming CCP showpieces.
The problem is that, once a negative reputation is set, it is quite hard to shake it off. Even if Valieva is cleared of any doping charges, there would still be suspicions about her. A number of figure skaters including Kim Yuna, the former South Korean figure skater have already accused Valieva of being a cheat, even when investigations are ongoing. Zhu Yi will have the reputation of being a US traitor, and a loser who had failed China. Her confidence in the competition is noticeably shakened by the haters in China, and their amplification by the Western MSM. Not everyone is as mentally strong as Eileen Gu, and the Western MSM took advantage of a negative situation in China.
