What do you do of researchers that pirate their own books, and tell you never ever to buy their books, but go to libgen? I have met at least 5 world-class scientists say that &quot;because I don&#x27;t do any money on it anyway&quot;, &quot;it&#x27;s a scam&quot;, and &quot;I wrote this book to be read&quot;. And tell &quot;it&#x27;s wonderful to imagine that this poor student read my book, and she was afraid to say she downloaded it illegally&quot;...<p>&quot;Piracy&quot; is a very nuanced subject, depending on what&#x2F;who you are talking about.
