Oh great. Another batch of "that does it, I am ditching Comcast". Note also that they didn't even have to do anything yet, just put out a press release, and the troublemakers (sharers in this case) are busy playing the Crack Suicide Squad - which is exactly what's required from the point of view of the ISPs. Just get them off your own lawn, and report progress to RIAA. There's always enough lemmings (who don't know and don't care) to pay the bills.
Now, if the comments were running to the side of "that does it, I'm getting Comcast accounts for everyone and the dog and sharing like it's 1999", that would make more sense as a response. Otherwise, get used to the periodical pronouncements - they don't cost anything and are having at least some effect.
