This is the Broadcast Flag. The Broadcast Flag applies to digital (OTA HD) signals; CGMS-A applies to analog signals.
You're right in that no tuners pay attention to it. That job lies with the software that runs that tuner, be it Media Center or a hardware DVR.
Blame the broadcaster, yes. But, complain to the FCC. In case anyone needs a reminder, what NBC and/or your local affiliate did is not legal: http://en.wikipedia.org/wiki/Broadcast_flag#Current_status
For those that want to read the legalese...

The FCC does not like it when broadcasters violate the rules.
