I think we have a case of survivorship bias. A considerable majority of the science-non-SWE crowd are de facto incapable of writing more than 100 lines of runs-in-my-notebook code. Hence, if a change/bug is necessary, it is much likelier to fall under a SWE jurisdiction, and hence is much more likely to be industrial code. Add to that a further confounder (tiptoeing a "no true Scotsman" here): academia is not a first choice of workplace for strong SWEs.
