Maybe you're missing the big picture...
Today, it's P2P protocols. Tomorrow it's your VPN session. Then it's your TV episode downloads from iTunes that competes with their satellite television or VDSL offerings. Then it's your VOIP traffic from another provider. Then it's your SSH session.
It's anti-competitive, anti-consumer behavior. Bell specifically advertises a service that doesn't slow down during busy times... And now they're CAUSING the network slowdown.
If they're not fought on this front, we're all fucked in the end.
