Today's stink

Okay y'all, have you seen today's stink in the writing world?
Amazon has released it's platform for making bank on fan-fic. 
Suddenly my Twitter and FB feeds exploded with people reacting to the news. You can find all the info on KindleWorlds HERE
Fan-fic writers will be able to upload and sell their stories based off other licensed authors/creators characters and worlds. So far, the major liscensor is Alloy Entertainment, the people behind The Vampire Diaries, Pretty Little Liars and more. We all know how Alloy cut LJ Smith out of the series she'd been writing, so this kind of a move doesn't surprise me from them.
I'm not sure how I feel about this. If you want to write fan-fic, more power to you. To each their own. Have a blast. I know lots of writers that do. I never have, unless you consider Broken fan-fic of Frankenstein.
Some camps say any publicity is good publicity. Others are saying mine-mine-mine! Others have so many thoughts and concerns they're hard to voice. I'm in an odd position to look at this now, and once I figured out what KindleWorlds is, my brain went into a tangled mess of what-ifs, and what-about-the-authors, and would-people-really-pay-for-its. Then, Fifty Shades came to mind, and I though Yep, lots of people woul pay for it. Which drags my brain further down the rabbit hole of. it's based off SMeyers world/characters, shouldn't she get a cut? It's going to be a film, shouldn't the CREATOR OF THAT WORLD get something out of it? KindleWorlds is opening up a big wriggling, gritty, can of worms.
You can read a great look at this issue, and some fab feedback on Chuck Wendig's blog HERE
A business-y look at itcan be found on John Scalzi's blog HERE
And a post by the brilliant Gwenda Bond HERE on how the properties in question so far are "packaged."

So what do you think? Good idea? Bad idea? Are you into fan-fic?
