Isn't the two phones thing mainly because of legal paranoia (I have no opinion on whether it makes any sense in that context)?

I don't think it's bad if people have wrong opinions, as long as they know what would it take to change their mind and are open about that (that's slightly stronger than "can explain why they think so"): often the choice is between having some opinions that might be wrong, or doing the default thing which might also be wrong. If one adheres to this rule, they are very likely to be convinced out of the wrong opinions.

(If someone publicizes their opinions using any sort of authority, then I agree this is weird, because it's actively harming society's knowledge.)
