Its actually much worse than what the author wrote about - he/she just messed up execution of roll-out. If they decided, the app was really not worth it, they could have unpublished it. However, even unpublished apps can jeopardize your account's standing by running afoul of a policy, which Google may have concocted long after the app was written. Unpublished apps in this state can get your account permanently banned. You have to support your apps for the rest of your life (if you care about your account).
