Who knows, but intelligence agencies could benefit from hacking it. Of course the dildo itself is worthless to pwn, but apparently many of the owners are connecting it to a mobile app, and dollars to doughnuts, the maker has not hardened the app against malicious inputs from the dildo and so it can probably be exploited, and from there, you might have lots of useful permissions (depending on how lazy the maker is) or at least a springboard to attack the rest of the iOS/Android OS. Plus, if anyone suspected they were being hacked from their dildo - would they ever admit it?
