An argument against “active” SETI rather than “passive” (sending vs just listening) is that we might give ourselves away to something/one that we would be better off if it/they didn’t know about us. Interstellar security through obscurity.

Active SETI? We’ve been broadcasting our location for over 100 years. When they get Mork and Mindy, all bets are off.
