So? People aren't a monolith. Maybe some can afford to give things away for free. Maybe some are living on the poverty line, but for whatever reason think the tradeoff of spreading something to more people (including those who can't afford to pay for it) is worth it if it means further reach for any number of reasons, including self-serving name recognition or selfless spreading of information they think is important to spread.
