You're blaming the Play Store for something that the app developers decided to do? Just because there's a hole doesn't mean it should be abused, particularly since Path is supposed to be from a "legit" company.
Yes I am. If there's a hole in IE allowing a virus to proliferate, don't we blame IE and get a security patch or switch to another browser? How is this any different? The root of the problem is Android and the Play Store.
