They do a lot more now. They're often networked and remotely upgradeable. Sure, you couldn't see the code in the microcontrollers in your old TV - the ones listening for IR signals and driving the LCD. But modern TVs do all of that and more; they have internet connections, some have cameras and microphones, etc. And even if you couldn't see the code in your old pacemaker (which I would say was still a problem), your new one probably has wireless administration and firmware updates. Those likely have remotely exploitable security vulnerabilities[0], and even if you have one inside your body, you aren't allowed to look at the code yourself.
