It's not designed to do that, no. But it is one of the goals, or at least one of the bonuses they expect to come of this. A big part of the freedom Stallman wants for everyone is the freedom to pay anyone who has the skills to work on your software, rather than the original creator having a monopoly on that and being able to charge monopoly prices to you.
That's a stretch. It's like saying the right to repair movement has a bonus of making cheaper phones because it introduces a point in which manufacturers can compete.
It's a long set of stretches, actually. People are just using the idea to either side with Wordpress or not, without understanding what it is. It leads to the misinterpretation of what free software is about (which I don't need to explain, since no one is actually interested in it here).
