I think that's probably the distinction though; EVOO has a much stronger flavour than the more plain OO. The latter is totally ok for a saute, or sweating off veg for a sauce etc, or roasting but as you note with a lower smoke point not so great for say doing steaks, or stir-frying - and far too expensive for deep-frying!
It seems like BS eh. Other folks I've seen are suggesting its just because they want to ditch easy anti-cheat to go with EA anti-cheat which (apparently) is windows only with no plans to develop for linux.
