My first thoughts, probably like many, were along the lines of "don't connect the TV to the Internet", but that is increasingly impractical as the article points out. Even more so, I can see why I might WANT my next smoke/CO detector, for example, to be connected and able to call the fire department if necessary. It might even be good if it had a mic/camera to allow the firemen to see/hear what is going on -- after all, if they take a look and see me standing there with a pole trying to jab the 'quiet' button and yelling 'false alarm!', they can avoid an expensive and time-wasting truck roll. Or, if they see smoke and people passed out on the floor, they can get it in gear KNOWING that there are lives on the line.
Basically, in short order we will (almost) all have bugged our own homes/cars/offices for perfectly good reasons. Or, if not for good reasons, than as a condition of our fire/casualty insurance policies.
Which means, unfortunately, that any technical fixes are attacking the wrong problem. What we need are behavioral/legislative fixes to make inappropriate access to these surveillance systems prohibited and punishable with real teeth. Punishments that breach the corporate veil, and are stricter in cases of official abuse than for 'ordinary hackers'. I wouldn't commence holding my breath for those laws, if I were you.
At any rate, go vote next week, and vote for 'less bad'. It's the best we can do.
