By editing, you licence your contributions under the Creative Commons Licence, giving everyone (not just Wikia) - the right to use content you wrote.

This is a better deal, because Wikia doesn't get any exclusive rights to stuff you wrote, and anyone is free to remix and make mirrors without getting into legal hasle, and it means that wikis can copy content from Wikipedia (properly attributed) without getting into trouble.
