We live in a World were, still (one would expect they should have learned by now) many if not most people listen to the opinions of people about things they’re not at all experts in (such as sports-people, actors and so on) because they’re “celebrities”.
Working in a profession which just so happens to be done publicly for an audience does not make one’s take on things outside that profession be any higher quality that those of any other random person.
By the way, it’s quite irrelevant if their opinion aligns or not with one’s own: the informational value of what they think is still zero.
