It’s weakness is that “only a single dissident group in an alien civilization, or alternatively the existence of galactic cliques instead of a unified galactic club, would be enough to break the pact of no contact.”
It’s also highly speculative. If we assume a vastly more advanced community chooses to not be seen by us, that makes it by definition nearly impossible to either prove or disprove the theory. For me, that’s a red flag.
That’s called the zoo hypothesis.
