The context Al described involves an employer and employee relationship,
not a client and a public CA. The employer in the example is the only CA
that will certify this individual as an employee. The token is probably
owned by the employer, not the employee. This is analogous to employee ID
badges. When my company changed from analog photos to digital ones and
reissued the badges, the employees didn't have a say in the matter. This
example is not a free market one inn which the employee gets to choose the
CA. While your comments are appropriate in some contexts, they do not
apply in all CA examples, including the specific one Al described.
