  GW200115 was the second merger of a black hole and a neutron star confidently
detected through gravitational waves. Inference on the signal allows for a
large black hole spin misaligned with the orbital angular momentum, but shows
little support for aligned spin values. We show that this is a natural
consequence of measuring the parameters of a black hole -- neutron star binary
with non-spinning components while assuming the priors used in the
LIGO-Virgo-KAGRA analysis. We suggest that, a priori, a non-spinning binary is
more consistent with current astrophysical understanding.
