Randy,It is quite possible that some are simply the victim of their own ignorance. I know of an ISP where one of their last-mile hardware vendors was pushing hard to get junior technical staff and senior non-technical staff to agree to share netflow data. When senior technical staff found out, they told the vendor that they would not share the data and to stop. The vendor persisted. After probing to find out what vendor was used in the core & peering parts of the ISP's network, one of the vendor's staff kindly provided netflow configuration to the junior technical staff, along with specific instructions to apply it to their transit/peering ports. The destination of the flows was a server under the complete control of the vendor, not the ISP. This was brought to the attention of senior technical staff and you can guess what happened.
The vendor is not one of the majors, they are still relatively young. I won't share the name on the list.
