See the tub of flavored couscous that looks like a cup of noodles? I
think this is the kind of product that is being advised against for
those trying to make "traditional couscous." I have never seen this
type of product in the US though. Perhaps it's more popular in Europe.
The couscous that one can buy in the states in a box or bulk is just
regular couscous which you can cook either by covering with boiling
water (quickly) or you can take the time to steam it.
