No, that's not what I said. You're right that journals, to some extent, also lends credibility to the publication, but it's not the source of credibility. What I said was that an article published in Nature will have many more views than an article published on a random WordPress blog.

Again, saying that researchers "agree to have it that way" ignores the structural difficulty of changing the system by the individual. The ones who benefit the most from changing the system are also the ones most dependent on external funding - that is, young researchers. Publishing in low-impact journals (ones that has a small outreach such as most open-access journals) makes it much harder to apply for funding
