This is a similar tactic to music labels seeding file sharing networks with phony mp3s, or the whole concept of "Rick Rolling" on YouTube, but of course a whole lot darker, as in includes a punitive violation of your privacy and a public shaming. Ironically, one of the mechanisms used to perpetrate this takedown is Android's own LicensingService and LicenseCheck routines, which are used to verify that an app has been licensed properly.
Symantec believes that this is the first example of an app developer striking out against unauthorized downloading in this way, but I suspect that it won't be the last.
