In effect, Above.net is (by filtering the ORBS probes) licensing every single IP
in their /16 to spam via the sordid and detailed means that ORBS works to
prevent.

This is an incorrect assumption? Please educate me as to how this is the 
wrong way to view this.

I am under the assumption that the said block on Above.net/16 didn't go into 
effect until ORBS itself was blocked - thus the resulting block on Above.net.
