Er.... you can get a considerable free SAMPLE of any ebook on Kindle or iBooks. And I have no objection to marketing campaigns that involve free copies. I've had them myself and will doubtless do more.

But you need to recognise - there is a difference between a publisher and author deciding to hand out free promotional copies and having them simply taken illegally. First time I've heard of stealing being called advertising by the way, or that I should be grateful for getting ripped off.
