It does seem that the "equality of outcome" criticism mostly is coming from spaces inhabited and informed by people like Jordan Peterson, Ben Shapiro and Dennis Prager. From what I have seen it is mostly used as a strawman because, as you mentioned, I too have not really seen anyone seriously arguing for equality of outcomes (if anyone has examples, please share).
