The assumption that all life in the Milky Way is extinct because we don't see any K3 civilizations is juvenile. The Great Filter assumes that all life in the universe decided they must become a K3, expanded into space and then were all wiped out by "something". There are so many variables in how a civilization develops that it feels like a generalization. It also assumes that a species goes extinct when civilization collapses. As for the communication issue, aliens may use different wavelengths to communicate and even then their messages might be encrypted.
