Then how comes the neutron stars collapse into black holes despite obeying the exclusion principle?

Different exclusion principle. For neutron stars, it is the Pauli exclusion principle (IIRC) which creates neutron degeneracy pressure. Enough mass and gravity can overcome it forming a black hole. The article is talking about quantum exclusion which happens at a much smaller scale. I don't know much about it because that exceeds the limits of my degree.
