Recognizing that my comment here is unrelated to the central question around whether companies should have this data, the irony for NetPropex (and the hundreds of other companies in the same business) of this kind of data availability is that it results in a lot of cold emails and phone calls that largely go ignored. Thus, as the data has become more widespread, it has become less valuable. Buying a list of people to contact, in my experience, is like throwing money in the trash.
