Does this explain why we didn't detect Aliens with SETI? Because their signals would be under the noise level (except for a few stars)? Indeed those stars that close enough to our interstellar probes will be also informed of our existence. "The transmissions to Voyager 2, Pioneer 10, and Pioneer 11 have already encountered at least one star, while those to Voyager 1 and New Horizons will encounter their first stars in the near future." https://arxiv.org/pdf/2304.07400.pdf https://arxiv.org/pdf/2304.07400.pdf
