This book/movie just as many of D'Nesh Dsouza's in the past is filled with many mistruth's and misleading conclusions. Now he has to recall the book because there are many legal ramifications that could be derived from it. He'll tell you it's the deepstate shadow banning him, or Barnes and Nobles doing it, but actually it came from his own publishing company to prevent a lawsuit.
Take this with a grain of salt, as it's based entirely on fiction and lies.
