A lot of plant milks are unsweetened, and there is a high and growing demand for these products—yes these companies want to make money, but it's not as if they were manufacturing the demand, they're merely capitalizing upon it.
Better yet is to make one's own oat milk; I agree that they're exorbitantly expensive, albeit (here in the US) the dairy industry is immensely subsidized and so we consumers don't see the true cost of our cow's milk.
