One way to get Congress to act on this would be to remind them of how Robert Bork's video rental history got released. They very quickly realized that they all had the same sleazy movies on their rental list and passed a law making it illegal to share them.

Call your Congressmen and tell them that their smart TV is sending screenshots of whatever they're watching back to home base, including stuff that's not streamed, and there might be swift action.

Better yet, hack Samsung and leak it to the press. That'll definitely light a fire under them.
