I am disappointed with Magnus. He is misusing the weight of his reputation even if cheating is a big deal in chess.
The first mistake was still choosing to play when he had reservations once Hans was invited. The second mistake was quitting the tournament and messing up the standings once he lost. The third mistake was making an insinuation through a tweet. The fourth mistake was resigning in two moves his next game with Hans.
Even though Hans is suspicious and untrustworthy, Magnus is taking on himself the authority to be judge, jury and executioner. If he is concerned about cheating being an issue, proactively bring up the issue, don't do it re-actively.
