Many telcos consider that sort of information to be not just private,  
but highly sensitive. For instance it discloses info about the ingress  
and egress points to/from their networks: where their SBCs and SS7  
switches are located, network topology, etc. The industry obviously  
needs to know this stuff. It's debatable whether it should be known to  
the general public.

A public NP database brings other concerns too. It opens up a new  
vector for slamming. It would publish info about which numbers are  
active and/or ported in a number block. If I was running a telco, I'd  
not be too keen on making that sort of information available to my  
competitors. It would also be too easy for telemarketers to mine that  
public database and harvest all the unlisted phone numbers.
