I was under the impression that the reason for that was that neutron stars lacked sufficient mass (and therefore gravity) to overcome the neutron degeneracy pressure. Or is that a related concept?
Indeed it is!
Degeneracy denotes the situation when all lowest energy physical states are occupied by a neutron, and hence blocked for others, and when compressing the star further one reduces the number of possible low energy states and thud forces some of them to occupy higher energy levels because only one neutron per state is allowed, and the low energy states are all taken. So compression forces some neutrons into higher energy states, and Energy increase divided by compression volume is more or less the degeneracy pressure.
