From reading the media coverage of the official announcement, Magnus hasn't changed his mind. He still thinks Niemann cheated in "over 100" online matches, and did so more often and more recently than Niemann admits. Magnus continues to acknowledge there is currently no definitive evidence Niemann cheated in over-the-board matches. Magnus continues to acknowledge he'll play anyone he is contractually required to play (including Niemann). My understanding is, OTB tournament rules require playing officially matched opponents - so there was no avoiding that anyway. Magnus (and everyone) reserves the right to publicly share their opinions in the future (meaning no gag or non-disparagement agreements for anyone). Chess.com reserves the right to enforce their terms and conditions going forward, which certainly still includes banning players for any future cheating. My take is basically everyone returns to where they were before that specific match, the subsequent related public statements and banning occurred. Everyone still stands by what they've said, no concessions or apologies are made by anyone. Everyone remains free to say and do what they want going forward, while also remaining just as responsible and legally liable for those statements/actions as they've always been. Any future cheating is still against the rules. The Chess.com rules as well as various tournament and association rules about playing required matches are still in force. The risk of defamation claims being asserted regarding future public statements (made by anyone about anyone) remain as possible as they've always been.
