Seems like a reasonable choice. There are people who won't buy their products if they are GMO, but the reverse is not true. (I doubt there's anyone who will only buy GMO products.)
People won't look for GMO products, but if you have two products with similar tastes and nutritional value, but one is more expensive because it has a "GMO Free" sticker on it, I'd bet most people would go for the cheaper option.
Not sure why you are getting downvoted, because you're absolutely right. Almost no one actually cares about "organic" and "non-GMO". Most in the United States are working paycheck to paycheck, but people on HN seem to consistently forget about their existence.
