If epub formatting is a problem, they can actually release a PDF version.

They probably not realise that printed book also can be pirated. Someone will painstakingly scan the book into PDF.

Good point on the PDF version, especially if Amazon allows PDF sales (instead a Kindle version). I am a bit surprised that pirating was a significant issue with the first book. Didn't they offer free or discounted versions if people requested they didn't have the money? If so, that might have gave people the impression that passing around copies wasn't a concern of the authors.

It's not even painstaking anymore, even with a cheap diy book scanner.
