They're even quite right :D I mean, at first, the Doctor seems a bit unsettlingly hostile towards humanity—unsettlingly for us, knowing him the way we do! And who changes him? It's not Susan, who was with him to begin with and does more following than changing—she changes and evolves herself, and thus makes her relationship with her grandfather shift, but she doesn't change him. Ian is important but theirs is a… man to man relationship? Ian and Barbara are the ones who open him to human companions, probably (at first they came for Susan, but then they were all a team—and I need to see how things will go to get Vicki on board to be able to go on with that reasoning) and Barbara has the more insightful, emotional part, she can soften him and deal with him (though Ian knows how to deal with him too—LOL, the beginning of Reign of Terror… :D). So yeah, Barbara probably strongly contributed to what he had with all the companions that followed :D Opening him up, so to speak.
