Arguably we've only been broadcasting outwards for something like 50 years, so the message hasn't gotten that far yet. There was a plot element in the book about using a technique to broadcast a message more strongly than terrestrial antennas alone. A spoiler alert another plot element in the book was that it wasn't just the one way broadcast, but a response & counter-response that allowed distant aliens to determine distance and direction. So I wouldn't quite say its disproven.
