Is there a reason no group has popped up to jailbreak the few major TV "OSes"? Given how prevalant this issue is it seems like a reasonable use of time akin to jailbreaking/rooting cell phones.
There's just no strong motivation to try to root my TV. I don't like my smart TV but I don't need to, because the smart parts can be "replaced" by any number of external devices. My point is that I suspect many would-be TV hackers are in the same happy situation.
