My opinion
The apps developers who are against jailbreak because they say the jailbreak is linked to the piracy, but they're just narrow-minded, dummies and fascists.
If they are against jailbreak, I'll remove their apps that I bought and I will take off their rating stars and will replace the positive comment for the negative. Like they did at Reddit against Go Daddy in the time of SOPA.
These fascist and functional illiterates don't know the difference between jailbreak and piracy, this is one thing and that is other thing. They will want us to be imprisoned, limited and narrow-minded and to support the limited iOS.
I don't consider jailbreak as piracy's alternative, but tweak and theme's alternative, so I don't want to be locked and imprisoned. I like freedom.
Apple and the anti-jailbreak protesters won't have any right of controlling me and my iDevices, because when once I bought or paid an iDevice with my money, it became belonging to me and not to them, my iDevice is mine and I do what I want with my iDevice.
You would be going to argue it's against Apple and DMCA policies, but if they control, sue and force me, they are violating the customer and civil, human and individual rights laws too.
