The English uses plural for corporations because they are referring to the mass of entities that make up the corporation (including people, brands, products). I don't think this is a grammatical problem, but a societal/philosophical viewpoint on what a corporation is. If you are American, of course it seems weird, but within the context of English society, it is internally self consistent with English grammar.
