Kik, the got-very-popular-very-fast cross-platform messaging app, was booted from BlackBerry's App World because of a breach of "contractual obligations," presumably breaching an obligation not to drive people away from BBM, RIM's own messaging platform which they hold near and dear to their hearts.
