Trust there is more as well. Like how Bell wanted to be the "port police" of Canada along with their throttling.
If you had an app (we will use FTP/FTPd as an example) that didn't use default port 21, then you got throttled as punishment.
So really what was going on was:
Communications not on standard ports = throttled
Undocumented, or new type, apps using a port = Throttled.
Encrypted communications = Throttled (very F'n Orwellian)
Game Updates = Throttled (they called battle.net/WoW cheap on their Bell.ca forum for not pushing updates via web or FTP downloads on port 21 only, and blamed them.)
In-line game communications where people talk to each other via head-sets = Throttled.
And the throttle in many, many cases throttled the line as a whole, not just the particular app causing the throttle. As Guspaz stated, his latency sensitive voip was throttled.
Yeah, hope they pay dearly for what they did and started. But, I doubt it. You know how it is.. Judge will have a lot of stock tied up in Bell for his retirement. Can't damage that.
