You have to feel sort of bad for him for being archaic/narrow-minded. From his perspective, he is a writer and just wants whatever he thinks he should or would normally receive for his work.
His comments about walmart and false prices are true - manufactured items like clothes and food are cutting corners elsewhere (social impacts + environmental costs + bad quality). But you can't apply that to an ebook? Problem is the publishing industry's outdated business model (but I guess he would be in worse trouble if he openly bashed them...)
