You're arguing against a strawman. In most cases, yes the manager probably is using wrong judgement, but there are valid cases where an employee would be disclosing information that could be used by competitors.
And I'd argue, the employee is tremendously valuable if that is the case, and probably should ask for a huge raise :)
