That's because it doesn't bear on the Fermi paradox at all. The Fermi paradox is about how information from/about aliens could have reached us in the past, whereas GP's comment is about how information from/about us could reach aliens in the future. Very different questions. Put another way, the mere fact that we can see the 94% of future-unreachable galaxies means they're a problem for Fermi, regardless of whether we can signal to them.
