If they have that much trouble taking the flags off of people's accounts, it wouldn't surprise me to find out that there's no codified correlation between "has the AP running" flag and the "is running a Comcast router+modem" flag.
I set up service with my own equipment from the start, and after all the account setup I received a dozen notices that all these wifi points were available. It was never specified as a "must have a Comcast router" condition.
