Most policyowners never learn that selling is one of four or five options, because the first company they call only profits from one of them. A carrier profits when a policy lapses. A provider profits when a policy sells. Neither is a neutral party.
That is the structural argument for talking to somebody who is paid to represent the seller. A licensed broker is a fiduciary, which means the obligation runs to the policyowner rather than to the transaction. Sometimes the right answer is not to sell at all, and a fiduciary is the only party in the chain with a duty to say so.
