  The following is a short comment on the recent claim made by van Dokkum and
collaborators about the existence of a low surface brightness galaxy,
NGC1052-DF2, not containing dark matter. A discovery used by the authors to
both reject proposals of a failure of Newtonian dynamics in the low
acceleration regime (e.g., MOND), and prove the dark matter hypothesis is
correct. It is shown here that the claim in untenable.
