Some articles on Principia Scientific are junk science, and its platform can serve as a counterweight to the highly politicized scientific "disciplines." Angry amateurs are often more accurate observers than those with a financial stake in a desired, but wrong outcome. E.g. Copernicus and Gallileo were accurate vis a vis the "accepted" heliocentricism of their time. Nature, whose revenues depend upon Big Science, first rushed to publication the fake study of the cheap but effective and safe lupus/malaria drug and then had to retract it two weeks later, but its damage cost many lives and is still doing so today.
