I think the time has come to introduce a new word into English usage. It seems to me that we need an active verb for the semantic range of "to be ignorant or uninformed." In Greek, Latin, and Spanish I can say that I do not know in the active voice without any helping verbs. But in English my only option is the now archaic usage of ignore. Hence I propose that we begin to use a new coinage: necognize. If someone says, "Why do so many people buy Apple products?" you can answer, "I necognize." Instead of "I don't want you to be ignorant" or "I don't want you not to know" you can simply say, "I don't want you to necognize."
