For a regular large sized company there are press pieces written every day that want an informative quote, shareholders cold-mailing you, customers trying all kinds of angles except the regular ones to get in touch, TV-shows that want your CEO on. All this gets managed in a way that at least suggests some uniformity in what you proclaim externally. Sure, there's domains that overlap PR / (internal) communication and marketing but generally they are treated as different tasks and organised as such. TL;DR - They manage one single external voice. There's value in that. As other point out, Musk is a communications study in and of himself.
