> But if the tool is closed, that should not invalidate any results in the paper. As I said in https://news.ycombinator.com/item?id=12100008 https://news.ycombinator.com/item?id=12100008: If it cannot be verified independently as far as possible, this does not mean it is wrong, but also should not be considered as science (since independent verification and the ability to do so as far as possible is central to science). Instead it is just a marketing statement with the author providing evidence for truth. Marketing statements are also not wrong per se (if they were, at least in Germany this would be a criminal offense because of the "Gesetz gegen unlauteren Wettbewerb (UWG)" (which according to the internet dictionary corresponds to "Act Against Unfair Competition" or "fair trade law")), but you strongly have to trust its author to tell you the truth, since you can hardly verify the truth independently.
