Don't think it's mudslinging .
Regardless of the type of NPA , from some point (MDA/DA) , to continue the approach ,visual contact with the runway must exist . As this was not CAT111 B NO DH ,the crew should have initiated a go-around if they lost visual contact at any time after this point .
The 3D/2D RNAV , GPS , LPV GBAS , AR etc. , the legality/requirements to commence approach , the notams , minimums are all nice discussion items , but would be probably deemed contributory . They didn't hit anything on the approach , they impacted the airport surface after supposedly being visual . Maybe they mis-identified the runway/taxi-way ? But this was in the landing / visual phase .
