> If the chess community decides to trust Magnus and his credentials without any proof, that's their prerogative, the concept of criminal innocence doesn't come into play at all here.
"Innocent until proven guilty" is not just a legal concept but a social norm. I'm a big Carlsen fan, but that same logic, applied to other domains, has led to witch-hunts throughout history, or character assassination/reputational damage when someone is accused of something but those accusations are never tested in court.
Coming back to chess, this isn't a casual situation with your friends, but a professional environment with norms and with money on the line. Imagine the same thing at your workplace.
Random non-experts taking sides here is inappropriate. Even many other Grandmasters have opinions on these accusations (true or false), but are refusing to state them publicly, preferring to let it play itself out, due to their respect for norms. Magnus is entitled to his opinion and to expressing them, but treating them as facts rather than accusations is just strange.
Chess cheating expert Ken Regan thinks Niemann didn't cheat. "Innocent until proven guilty" obviously applies.
