I find it weird to witness all the drama, pomp, and circumstance around the professional chess scene. It is a board game. I couldn't care less if they decided to play pool-side with swimming trunks and flip-flops.
Magnus' priorities are clearly that he's won everything up for grabs and plays for fun. He doesn't need to worry about money nor rules set by a sport federation stuck about half a century in the past. If only the rest of us were so free!
What I was saying is that I think Magnus was protesting, and doing it as a publicity stunt. He didn't forget anything. He didn't expect to be given a pass.
And FIDE also weren't being dicks by enforcing the current rules.
Attending corporate sponsorship events sounds soul crushing for someone so free, not fun. His priority is keeping his sponsors happy as he tries to fire up his new thing.
