Kramnik engaged in a dedicated bullying and a smear campaign against Danya for a prolonged period, without substantive evidence, and never let up. When Danya explicitly stated in multiple interviews that Kramnik was seriously affecting his mental health, Kramnik persisted in his harassment. When Danya's mental health ultimately led to his death, Kramnik tried to put the blame on everyone but himself, including Danya, his friends and family, even the entire chess community. According to Kramnik, it seems like he is the only one who's completely blameless. It's good that he's being punished, but I think the punishment is too mild. In my opinion he should be stripped of all his titles, including his world titles.
The sad fact is that Kramnik is a pathetic narcissist, who because he's a shadow of his former strength, and a slow old man, gets easily beaten in online blitz, and then accuses people of cheating to protect his wounded ego, because he wants to pretend he hasn't declined.
