Sometimes a small fee attached to a service can help with accuracy.
In other words, it keeps people paying attention to what they have.
Case in point:
We offer various services at work. Payment for those service switched to a "per full time employee" charge. It was touted as a great thing, reduced paper work, simpler to provide service, no additional charges, just one fee.
Problem was, it took away all responsibility for the end user department to track if they really needed said services or not. There was no reason for them to disconnect old services that were no longer in use. Made a huge record keeping mess.
I personally like the idea of the FCC doing this. Clean up the databases, get rid of all the defunct users, flush out unused services. At least that way, the FCC can get accurate estimates of how many real users they have.
