Even more basic than that, why do we think radio/photons are the most efficient/effective way to communicate for an advanced civilization? Why would they be using them in the first place? We already know neutrinos can travel through most mass, so modulating those would let you transmit through the Earth and Sun with lower latency and without a repeater constellation routing around the object. Whatever aliens might be using to transmit information is likely more advanced than we're able to detect.
