All this chess.com stuff is a bit of an aside. I don't see any remotely good evidence he's cheating over the board. For a start it's a lot harder to do, and there's nothing really in the games to suggest it. He's made plenty of human errors where you're supposed to make errors. The GMs that I have seen look over the games don't seem particularly convinced either.
If the chess.com stuff stood on its own merit as important they should have been dealing with it themselves, not just throwing everything at the wall because Magnus has spat his dummy out. They already banned him for it. Whether the punishment fit the crime I don't think it generally does, they're too lenient, but time was served for it. The Magnus tour also gave Hans opportunities after the chess.com cheating was already known in the community so that's..strange?
To me it's Magnus throwing his weight around because he's unhappy he lost and he couldn't get over his own paranoia due to Hans chequered history and now he's involved with chess.com they're all piling in. For once I think he miscalculated his response here and put a massive dent in the tournament to boot.
