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.
