Zebras, intransigence & semantic apocalypse: problems for dispositional metasemantics

Complete information dispositional metasemantics says that our expressions get their meaning in virtue of what our dispositions to apply those terms would be given complete information. The view has recently been advanced and argued to have a number of attractive features. I argue that that it threatens to make the meanings of our words indeterminate and doesn't do what it was that made a dispositional view attractive in the first place.
