Comment on: Cosmological black holes are not described by the Thakurta
  metric
  Recently, H\"utsi et al.[arXiv:2105.09328] critiqued our work that
reconsidered the mathematical description of cosmological black holes. In this
short comment, we highlight some of the conceptual issues with this criticism
in relation to the interpretation of the quasi-local Misner-Sharp mass, and the
fact that our description of cosmological black holes does not impose any
assumptions about matter accretion.
