Let's say, for arguments sake Henrin, you write the next great American Action Novel. Publishers are excited, Hollywood is waiting to make your story the big movie. The pay out from all this will let you retire from a real job, secure your financial future and you can write for life.
There's a catch, they publish your book digitally. If it makes a million sales, all your good things will happen.
A year goes by, despite the hype, the forums and fans... you're book sells only 750k copies. Publishers leave, Hollywood decides maybe you aren't all that. The future you wanted slipped away.
One day, at home you're pursuing your favorite property sharing site, as you like to call it, and you see your book has been "shared" 2-3 million times...
Yeah, and that really does play out in the real world like that in many ways.
All the responses have been aces everyone, but those in favorite of "Sharing"... I see a bunch of self justification for what you know is wrong. Sorry that's how I read it.
