Which is a con of licensing mentioned in the text?

The con of licensing mentioned as interfering with freedom of expression highlights the tension that can arise between maintaining professional standards and the individual's right to express opinions or ideas freely. Licensing often involves regulatory requirements that may constrain how professionals communicate or operate within their field. For instance, professionals may feel compelled to adhere strictly to licensed practices, which can limit their creativity or personal expression when addressing issues in their work. This concern is particularly pertinent in fields such as public relations, where effective communication is critical. By imposing licensing requirements, the potential for creative and varied approaches to communication may be restricted, leading to a more uniform but less diverse discourse.
