I am fascinated by this quote. I think it’s the most beautiful quote, in it’s terseness, I’ve seen since a long time. Wish I invented it!
It is not, though, the motto of Wikileaks, it’s taken from the section on Reproducibility of this Open Science manifesto.
To me, this quote means that validation is superior to peer review.
It is also significant that the quote says nothing about the publishing aspects of Open Science. That is because, I believe, we should split publishing from the discussion about Open Science.
Publishing, scientific publishing I mean, is simply irrelevant at this point. The strong part of Open Science, the new, original idea it brings forth is validation.
Sci-Hub acted as the great leveler, as concerns scientific publication. No interested reader cares, at this point, if an article is hostage behind a paywall or if the author of the article paid money for nothing to a Gold OA publisher.
Scientific publishing is finished. You have to be realistic about this thing.
But science communication is a far greater subject of interest. And validation is one major contribution to a superior scientific method.
