Carlsen is seen as having drawn unwilling participants into his drama (he withdrew from a Swiss style tourney this forfeiting several games), he is seen as passive-aggressive for not making any direct allegations, and there is an arrogance around Magnus believing he knows better than the chess community and organizers about how to deal with former cheaters when they have quite obviously chosen to forgive and trust Hans.

I’m sure some people think Magnus is very brave and courageous for what he’s doing but my general impression is most people don’t approve of Magnus’s methods.
