How might a high population of life on rogue planets relate to the Fermi Paradox?

Answer

They are exceptionally difficult to detect using current exoplanet-hunting methods reliant on stellar light

If life primarily exists on dark, isolated rogue planets, they are exceptionally hard to observe using established techniques focused on stellar light curves or atmospheric spectra caused by starlight, thus contributing to the silence implied by the Fermi Paradox.
