The context in which this happened matters a lot.

There have been tensions between the FIDE organization and top players like Carlsen since the latter have been promoting an alternative chess organization around Freestyle chess (aka Chesss960), which has slightly different rules.

I.e. this is less about "dress code enforcement" and it is more about "Carlsen is fed up with the FIDE organization in general".

Chances are there also is a commercial angle to it. Magnus has commercial interests in https://playmagnusgroup.com/, which is somewhat at competition with the FIDE.

If I understand correctly Play Magnus Group was acquired by chess.com in 2022.
