You keep saying "publication". You know that in my opinion, in science, the question of publication has been settled. In the case of teaching, however, professors hired at francophone universities must give courses in French. If a student pays tuition fees to a francophone university but their chemistry or physics course is taught in English, that is a false representation. In that case, they might just as well have gone to an anglophone university.
