Short version: Trickle-down core technology stack and less synergy.

All the reasons given are logical and sensible, but there appears to be a growing structural problem in the technology relationship between WMF and Wikia. At some point it may make sense to completely fork Wikia's engine from WMF's, but hopefully some better arrangement can be worked out.

One thing I like about WMF is that they have a much more careful, less throw-stuff-at-a-wall-and-see-what-sticks approach, but I guess ultimately they have more resources and more dedicated/powerful volunteers.
