It's only a problem is he's unmotivated and he wants to write. If he just decides not to write then, it's pretty simple for him to move not. Not so for the readers who pirated his first book, found it expanded their minds and now are hungry for more by the same author.
That might be frustrating for his would-be readers, but in the same way that it’s frustrating to me that there aren’t many great small flagship smartphones. It’s a bummer, but I’m not going to genuinely complain that I’m being wronged because there aren’t enough people out there willing to buy a small phone.
I am happy to complain that we as a society have limited ways to reward people who share knowledge that we all benefit from. The answer, if you ask me, is to levy a tax and let citizens decide where the money goes via quadratic voting.
His readers are at loss. Their book won’t come into existence.
