I'm not arguing for that since anyone who is steeped in the topic can determine a general "change history." I didn't claim it was someone in their backyard, did I? No it is job stability. No one who doesn't believe in string theory will get a specialized degree in it, for example. HN seems open to criticizing generalities like, "science publications are often fabricated" or "academia is too closed," but you start getting too specific and the folks who have most of the academic budget for a mainstream paradigm will come out of the woodwork to discredit skeptics using straw man arguments, ad hominem attacks, and various disingenuous methods of thwarting reasonable opposition. For example, just look at the percentage of worldwide physics funding goes toward big bang based fields vs the rest.
