Ethics question

This may seem like a silly question but having a debate with a colleague regarding a hypothetical scenario and if it would be considered an ethics violation. Obviously disclosing information about the exam is a violation but what about a general statement saying the exam is too difficult or the cfa institute wants to limit membership (in essence statements of opinion) - would those be considered violations? Appreciate any color.

This is not violation.

Last standard mentions that is is not a violation to express opinion.

even below is not a violation.

“CFA sucks”
