We already know that we aren't going to accidentally eavesdrop on extraterrestrial communications. Those are almost certain to be very tightly focused and using some sort of transmission and modulation scheme that will make them impossible to decode or even perhaps to recognize as a signal with our technology (much as, say, modern DSSS technology would look like noise to humans even a few decades ago).

SETI has always been about the attempts to discover signals that are intentionally broadcast to civilizations with our level of technology.
