I think it's different. Cutler's alleged distaste for Unix (don't have first-hand knowledge) was that he viewed it as basically a product of ivory tower academics as I understand it.
There are various versions of the relationship between Cutler and Unix. Showstopper has one. Bryan et al may have another. And there are doubtless multiple others.
