Zynga completely abused the product. I started getting requests to give them more rights on facebook, which I solved my signing in with my email - then they started to send me push messages about weird things - I've heard they even asked for read/write sms rights on Android devices. I can only see it one way - Zynga might make cool games, but they are hardcore abusing regular people - also non-techinal people unlike us, that does not realize the outcome of granting these priveledges.
