Magnus is the top most authority on how humans play chess. He is not just gifted, he works insanely hard and he got to the top by being extremely unforgiving and harsh on himself when he made mistakes.

The idea that magnus was being a crybaby was always a joke for people familiar. And he's completely justified in drawing a line and saying he'll not play against people who cheated online or offline repeatedly.

His response and chess.com report are both extremely nuanced and very professional. People just got impatient.
