Wikia and Sony Playing Licensing Mind Tricks
TuringTest (533084) writes "Popular culture website Wikia originally hosted its user-contributed content under a free, sharealike Commercial Commons license (CC-BY-SA). At least as soon as 2003, some specific wikis decided to use the non-commercial CC-BY-NC license instead: hey, this license supposedly protects the authors, and anyone is free to choose how they want to license their work anyway, right? However, in late 2012 Wikia added to its License terms of service a retroactive clause for all its non-commercial content, granting Wikia an exclusive right to use this content in commercial contexts, effectively making all CC-BY-NC content dual-licensed. And today, Wikia is publicizing a partnership with Sony to display Wikia content on Smart TVs, a clear commercial use. A similar event happened at TV Tropes when the site owners single-handedly changed the site's copyright notice from ShareAlike to the incompatible NonCommercial, without notifying nor requesting consent from its contributors. Is this the ultimate fate of all wikis? Do Creative Commons licenses hold any weight for community websites?"
CC-BY-NC licensed Wiki's are not included in content presented by Sony apps (only CC-BY-SA ones are). Disclaimer: I used to work for Wikia on this project so have first hand info about this.
This applies only if contributors provide their contributions under the License. TV Tropes Foundation now claims that contributors provide provide their contributions not under the License but instead under assignment of copyright: "By contributing content to this site, whether text or images, you grant TV Tropes irrevocable ownership of said content, with all rights surrendered" except for fair use. So TV Tropes Foundation becomes the copyright owner, and it licenses your edits back to you under the License.
More or less the same thing happened with Gracenote as I recall.
However, that doesn't really address any of the issues that GP raised.
IANAL either, but generally speaking, a "licensing agreement" is a contract. And again generally speaking, one is not allowed to change the terms of a contract and make them "retroactive". At least not without the consent of all parties involved. If you did, it would no longer meet the very definition of "contract".
I mean, just think about it. Could your cable company say "We're going to make you a 'retroactive' customer and charge you for all past years as well"??? Of course not.
My sites free. I pay to host it. Anyones free to go there, download my content. I've no intention of ever applying ANY license to any of it. You can even use it for commercial purposes if you like. I don't care. If you want to be nice you should throw in an attribution though.
If you don't apply an explicit license, standard copyright applies, and that is "all rights reserved, no copying allowed beyond fair use." I'd recommend applying the CC-BY license or the GNU All-Permissive License to your pages.
