On RoadRunner I think you're confused, this was always a marketing brand name of Time Warner Cable Internet. At some point they stopped using the brand name, but the same people\ownership are still in place, even if it uses a different brand name now.
@Home was also different, in that Comcast and others paid them to build out their network and once it because big enough they just took the network back that they already paid for. This was in the original agreement with @Home and @Home still runs Internet services for other smaller ISPs (though it's now part of the Excite family).
There was no cancellation of franchise rights in either case.
