That's the way forks work in the open source community. Remember the license change last year from GFDL to CC-BY-SA ? Under GFDL, Wikia was obliged to provide database dumps. Under CC-BY-SA, we can only hope that the threat of destroying their "Open Source Content" reputation will keep them from considering such underhanded tactics. As far as I'm aware, Wikia has fully supported wikis that wanted to fork off in the past.
