|  Some have taken issue with my use of the word 'Abuse' with regards to Cox and Comcast using the RST flag to tear down TCP connections.
It's an 'abuse' of the specific purpose the RST flag in a packet header.
The RST flag is to be used only by an endpoint in response to a SYN packet when a port is not open, or if an endpoint detects an unrecoverable error condition that requires both endpoints to drop the socket and start over. No intermediate devices should be sending RST and because of this fact it is an abuse of the RST flag.
