Except we are already violating this by sending things out into interstellar space.

  Not just “some things”: Nudes, a mix tape, and directions back to our house.

    And a car that doesn't work. Imagine the civilization that finds that in a billion years. They will spend countless hours trying to figure that one out

  If you haven't already, read "the 3-body problem".

  Yeah, seems to me there'd be a bit of time in there before any civilizations decided it was better to stay silent. But that time might not be astronomically relevant.

  We really haven't sent anything that's very 'loud' out into space though. A little probe without even an active transmission process is not a very loud signal. All of the electromagnetic noise we emit is barely perceptible above CMB once you get even a small distance away. On a galactic scale, we have been almost entirely silent so far.
