seanan_mcguire posted about this at Go then, gunslinger; there are other worlds than these: Seanan ponders Amazon Worlds. I commented with some links to other posts on the topic and some comments beyond what I made before. At the time, I was finding it difficult to articulate something that bothered me-- as a moral matter, not a practical one-- about Amazon acquiring the rights to OCs used in Kindle Worlds.If an OC is created in KW, that character might well owe its existence to the openness of the world. To then lock away something created because of openness seems perverse to me, and...
To the best of my understanding, this is what could happen:
First, of course, the canon was created, and then licensed.
To create derivative works of That Particular Canon for Kindle Worlds, a fanficcer merely writes the fic and (possibly, if KW is dealing in good faith) receives compensation for that derivative work, on terms agreed to by the rights-holders and without preventing them from creating more of the canon or licensing others to create derivative works, and with the rights-holders also receiving compensation.
The fan introduces an original element.
That original element can be used derivatively by the canon-creators (or, rather, the rights-holders; in many cases, they aren't the canon-creators), without compensation to the OC's creator, without the OC's creator being allowed to use xyr own OC in xyr own for-profit works.
It seems, then, that this is uneven. One side appears to be sharing more generously under these terms than the other.
