I think if anybody's to be commended for their principle it's probably the organisers? They have their dress code, he violated it, was warned, continued to violate it, and they enforced the rule despite his name.

If "wearing jeans is not okay for someone playing chess" is a principle, it's a pretty stupid one. Being consistent about enforcing dumb rules is not a virtue when the alternative is not to have dumb rules in the first place
