The important thing is that the vote is correct, but I don't think the statement really makes sense. Just because players have been on loan at Morton doesn't mean that they, their parent clubs, or the national team really saw much benefit. You could make a case for Barrie McKay's career being set back by his loan moves (albeit that's down to his terrible attitude) as much as anything else.
Still, nitpicking a bit - the important thing is that the current proposal has another club voting against it.
