I would ask them two questions.
One, how is it fair that their IPTV traffic that traverses the same network, the same core network, can be exempt from UBB when it's providing a huge load? We all know how intense a video is. Anybody who's ever streamed or downloaded knows that. How is it fair to do that and yet impose it on everybody else if they want to do something similar?
The other thing I would ask, which is an even more basic question, is how is it that they're doing this when nobody else in the world is doing it?
