It was recently suggested (arxiv:2410.06604) that the small value of the dark energy of the universe could be explained in terms of the scale of neutrino masses through a simple quantum field theoretic mechanism. I clarify that the quantity computed is only a threshold correction to the vacuum energy at the low $m_\nu$ scale, and therefore cannot explain the magnitude of the vacuum energy.
