It definitely does!
It was a bit surprising that you did not offer a freely downloadable pdf file for the book yourself. Anyhow, if the book is minimally relevant it will appear on library genesis for all to see. Time to stop pretending that this does not happen.
For an anecdotal data point, I systematically buy one or more printed copies of scientific and technical books whose authors distribute freely a digital copy. For example, GNU manuals and FSF publications, as well as many math books, including quite famous text books (my favorite, Ian MacKay inference textbook where you can download even the .tex sources!).
I still hesitate where to buy the physical copy of your book, though. It sells in amazon for 25EUR, but the sole review says that it is a low-quality print-on-demand thing. I would happily pay 50EUR if I was sure to obtain a high-quality print, well bound, with crisp text and figures and pages that do not fall apart. But then again, I'm a fastidious bibliophile and probably not representative at all.
