Chess.com must be really struggling for money if they have to wait for a non accusation of OTB cheating to run their anti-cheating algorithms on a player’s games.

Which they obviously aren’t. Which means that they have found nothing new in the “review”.

The more obvious answer is that Magnus is pissed, and as a part owner of chess.com and biggest draw in tennis, chess.com wants his continued participation and so is kicking Hans out.

They may have justification for it, but it was clearly not enough of a justification to act on before Magnus decided to get all pissy on losing.
