which is something people rarely talk about, after all, space isn't completely empty, there are gas clouds of various compositions, stars, black holes and many other objects that can disrupt radio signals and hide evidence of large scale megastructures or industrial activity.

Couple that with our detection abilities as they stand now and we may simply not have the equipment sensitive enough to detect such signals through the interference patterns. They would appear as random noise, rather than artificial signals.
