Tons of authors are worried about this right now (including my wife, who self-publishes on Kindle Unlimited). There's stories of major authors being taken down every few days because copies are being found on pirate sites, which they can't control. I want to say there was 4 authors my wife heard about that had their works taken down suddenly from Kindle Unlimited just last week because of this.

There's some software out there that's like $7/month per book I think, that's supposed to help find and help issue Cease and Desists for this stuff, that my wife is seriously considering getting to at least point to in case hers gets taken down to show she tried to do something about it. Problem is, for each book she releases, that's an extra $7 a month she's paying. Feels like mafia extortion money almost.

There's even been some anger lately because of pirated books that keep getting uploaded on Scribd, who now have an ebook subscription service, so Scribd is making subscription money off of pirated ebooks.

It's one of the stupidest things I've ever heard of, that Amazon punishes authors for this. If they carried process over to tv, movies, music, etc, they'd have to take down their entire catalog because all of that has pirated copies out there somewhere.
