It's worth noting that proponents of moral naturalism, which is at least a position taken seriously in philosophy, do not find any problem with the is/ought problem. Furthermore, moral realism in general doesn't have a problem with it. The fact that they are "long thought" not to be a discovery of truth (by whom?) does not settle the question, but personally (as a moral anti-realist) I agree with you.
