well, there is a whole book about piracy, DRM and selling stuff on the internet. https://en.m.wikipedia.org/wiki/Information_Doesn%27t_Want_to_Be_Free

So I won't add much to the topic, what I can say is that this is about being pragmatic. There is some people who's gonna spend their money on books but it requires publicity (polemic topic) and subsidizing creativity with our own money (another controversial one).

Otherwise it's a difficult discipline /profession /industry
