Of course they want to keep it proprietary. The only reason to not have it proprietary is when you can't get away with it (for example, if Google came out with GoogleAuthor for Android tablets, and it was proprietary, people would only laugh). Only by having it proprietary does it open the door for helping iPad get a strangehold on the tablet market, just as Windows/Office did with PC's. Without proprietary, you can't get there from here.
