Don't listen to that whole "we have always had limits", they haven't. They had some peak hours thing between 5pm and 1m but were unlimited all day long and offered unlimited commercial accounts. Speaking with their techs after getting the notice I was told they are going to be enforcing this starting now and commercial accounts will also be limited.
Now we do and there is no way around it. It sucks but what else am I supposed to go? Have no internet? I am just a slave like everyone else to their ISP, they can do what they want and I am forced to accept it.
This is the future. Restricted internet and high penalties for anyone who dares not use cable tv as their primary form of television entertainment.
