He didnt have much for the case of defamation, which is why he lost that case against Magnus. It is however fair that Magnus has no proof for him cheating in OTB matches, and keeping that up without proper evidence could end up in a successfull defamation lawsuit.
This doesnt necessarily change anything for OTB tournaments, which are regulated by FIDE, who had the report on their investigation postponed until October (I believe).
I agree it is wild his chess.com account was reinstated after their report in which they claimed to have proof for iirc hundreds of times cheating in online matches!
