Growth hacking and marketing are all about targeting the right products to the right potential customers. So as tools they are fine and add value to society, because without them product discovery would be less efficient, and there would be more big companies keeping their claim and less chance for indie hackers. Some people may use them to promote bad products, but I would argue that those businesses are the problem, not the tools.
