Ignoring the security through obscurity mess, the more salient point is that there are classes of problems that cannot be solved at present without a locked down client. If solving such a problem is the entire function of the device I don't know that I'm against this. Technology will eventually solve such problems (thin clients or fully homomorphic encryption) but these have serious issues of their own.
