> Every other society realized it at the same time? Which would imply every other society is roughly born at the same time, which sounds unlikely. So some of them (like us) should not yet have discovered the danger of broadcasting signals.
Yeah, that's the Dark Forest book in effect.
If you broadcast, other civilizations could attempt to destroy you, so most civilizations find some way to dampen transmissions or limit them somehow.
Precisely, and in the Dark Forest book we (humans) did indeed detect radio signals from other civilization very early after we built the radio telescopes capable of doing so. So the fermi paradox is not present in this alternate reality.
In our reality we haven't detected anything yet, hence the paradox.
