I'm just starting to see this behaviour from charter.net, a cable 
TV/Internet company.

I haven't spoken to them yet, but I was planning on it.  However, I don't 
expect positive results.  After all, I don't see any way that this was 
anything but a conscious decision on their part, and I can't imagine that 
my voice, even if it did reach decision-making ears, would sway their 
already completed thought process.
