Getting bought out by Apple is basically their only option for mainstream success on iOS because of the way iOS's keyboards are locked down. A keyboard like this loses a lot of its usefulness if every app has to implement it via SDK separately, because it is far better to have a consistent keyboard system across all apps.

So I'm cynical too but from a different angle -- Apple has already fixed the game when it comes to alternate keyboards (unlike Android where you can install 3rd party keyboards that work system-wide).
