Not necessarily. It might merely reflect a too-narrow definition of broadcast baked into current assumptions. Right now SETI is looking for its lost keys near a street lamp, because "that is where the light is". Not to fault that approach, but I would not make any larger inferences about their lack of success.
To each their own. Finding unique pond scum on Mars would deeply horrify me.
If life independently emerged twice in one system then the paucity of intelligent life's cosmic signature means something happens between formation and broadcast with deafening regularity.
