Just because the standard lisp reader is readily available doesn't mean you should use it for anything else than code or small chunks of trusted data. Was there ever a question of using regular s-expressions in the same way as json? I don't think I have ever heard people suggest that. Most people either talk about using (read ...) to read trusted config files (which is fine) or to define an s-expression format to address specifically the complaints of the article. As others have pointed out, there is nothing stopping a lisp reader from reading an alist as a hash-table. That is an implementation detail...
