In the presence of each and every person living in an industrialized society are multiple devices running embedded software that is difficult to modify. Those devices are programmed using more flexible systems which to this very second are programmable any way you like. Where is the outrage over the hacker unfriendliness of my refrigerator? The iPad, iPhone, Android, and comparable devices are a hybrid of PC-like and embedded systems. The tradeoffs were made for reasons outside of anyone's programming/hacking needs. Should you want jailbreak a locked down device much of the work has already been done for you.
A hacker's "freedom" to poke around in the system has been traded for the freedom of an average person to use the damn thing without worry. This argument about post-PC devices and whether or not they're good for hackers is tired. Be thankful that powerful, accessible devices are being put in the hands of millions of enthusiastic people that you have a chance to influence and affect through software and services.
Finally, let's address the specter of censorship. This is brilliantly simple (in the United States at least). Address the entity censoring you. If it's a private entity then accept that they have no legal, ethical, or moral obligation to give you any access to their customers (much less complete access). Roll up your sleeves and compete. Should you be dealing with government censorship then pursue justice in whatever way your heart guides you.
But please stop whining.
