Source-code freedom is user freedom. It's effectively a sort of guarantee.

The additional freedom that BSD licences provide is freedom for developers to do what they like, not anything to do with users.

(The biggest practical advantage of a BSD licence for most developers is that if you use one when publishing your code while you work for a company, you yourself will still be able to reuse that code after you leave.)

Developers are users.

Which is why it makes sense for developers to license their code under licenses that guarantee user freedoms - so that they themselves can benefit.
