Yes, that's another example of tuning the parameter-space for a possible answer, just an unlikely one. Yes, maybe the Milky Way is just chock full of highly advanced technological species who have all made themselves very hard to detect and none of whom have any interest in communications with other intelligent life. But a simpler explanation that has many more paths to being true is "there's nothing out there." To be clear, I don't think the evidence suggests near-certainty here. I wouldn't say that there's a 99% chance that we're alone in the galaxy. But it's also not a wide open field. There is some evidence, and so far that evidence suggests that we're likely alone.
