I get it Ca, I happen to be one of those network ops folks that likes to 
sleep at night. However, I've never thought it was a good practice to 
break applications in fun ways for my customers to discover on their own 
and I've never sold someone a 150Mbps package that actually only 
delivers 10Mbps for certain applications. Regardless of the intent, ATT 
and Cox's policies are not transparent, open, or neutral on this topic. 
This leaves us to speculate on what their intentions might have been and 
whether their actions are an appropriate response to any concerns they 
might have had.
