From their other posts it seems to me that hogposting is arguing for Marx to be treated as Newton is in physics - the vast majority of physicists and engineers don't read Principia or Opticks. Newton's ideas are foundational, but no-one studies "Newtonism". The central, lasting concepts have been modernised and synthesised with the broader study of physics, and there is definitely pushback in some circles at the suggestion the same should be done for Marx.
I don't think this is really Robinson's point though; he just seems allergic to anything related to Marx.
