The problem with this hypothesis is that we would have picked up the signature of intelligent life before they were able to mask their presence. Like, even if we got to the point of being able to mask our existence, aliens would still pick up our old radio signals. It's important to realize that when we're looking into the observable universe, we're technically looking back in time.

Technically true. But it's also very easily possible that the ones who broadcast get snuffed out fairly quickly (on cosmic time-scales, at least). It would be pretty easy to do that with relativistic kill missiles without ever revealing your own location. And the ones who developed in such a way as they realized the dark forest possibility before broadcasting would simply remain unknown to us.

Keep in mind that our own broadcasting has only been going for about 100 years. To put into perspective how far our own fingerprint has traveled into the void:

It's extremely easy to believe even if there are hundreds of civilizations just in our own galaxy broadcasting freely, we wouldn't have received any of their signals yet. Space is just SO. FUCKING. BIG.
