You know these apps rely on very very long lists of domains to be blocked that lots of people have gathered during the course of years and that the developers of those adblocker apps just took those lists for free? So that's what those apps should cost.

That's incorrect. Peace for example negotiated a contract with it's rule list provider (Ghostery) to share profits. So this will help Ghostery to maintain a quality list. I'm not sure that the other blockers haven't negotiated similar arrangements. Unattributed accusations of leeching aren't very kind.
