This weekend, it was announced that The Wall Street Journal's iPhone and iPad apps and the universal Kobo e-book app would soon support Apple's in-app subscription policy, suggesting that the Cupertino, CA company is beginning to clamp down on those resisting the change. Following the announcement, Kobo updated its universal app, removing the Kobo Store from within the application. As of this moment, The Wall Street Journal's iOS apps have not been updated.
