I'm asking if there is any practical impact which results from this rights violation? Is anybody losing anything as a result of it? If the answer is "no" then one could ask "then why does it matter?".
Can I argue the same way when I am in court for software or book piracy ?
Telling the Judge I would not have bought the book anyway ?
It does matter because the contributors in GPLed Open Source projects had other motives spending their time on the software then helping Bookeen to make profit !
