You also have to consider that you don't know all the details of the Sinner v. Battaglino cases. Your inclination is to believe that there is doping. That is no more "right" that Margaret and me believing that it could have been inadvertent. As to the Olympics, etc, you are leaping to conclusions.
You said above that they're protecting the #1. But they brought the story out. You've said in the past that they protect "top players" (euphemism for Nadal, and lately Djokovic) by burying them completely. Well, they didn't bury the Sharapova story. Nor this one. You're giving Maria credit for copping to it, but she was trying to get ahead of the story, saying she'd "missed the memo" that it was newly banned. She couldn't deny she'd been using meldonium for years, pre-ban. Nor can we ignore that she never had the same success after.
