Seems early to freak over this. We have no idea what this will look like, or even what that whole sentence in the pic says. If they throttle everyone down to 4-5mbps when there is mass congestion, so nobody gets kicked, awesome.
OTOH, if they throttle everyone down to dial up speeds for no reason, then screw'em. It'll be considered a material change in the service, and everyone will run away without getting hit with an etf.
I'm all for responsible, neutral network management, so I'll just wait and see what actually happens before going crazy from a leaked pic of an incomplete sentence.
