I would say that it is a kind of investment for authors. Judge for yourself: it is absolutely unimportant what kind of content it is (article, photo, tutorial or recipe), the developers adhere to the fact that, because of their professional content with an excellent reputation and generating income, must be guaranteed to be protected.
if the project team considers potential authors only those who already represent something of themselves, then how to deal with those who are just beginning to comprehend the world of creating masterpieces? Can such an author be part of this project?
as far as I understand, even a non-professional author in this concept is considered as a strategic link. Each new person brings some kind of diversity and a new wave, therefore, to attract such authors, a new approach based on justice and transparency is needed.
