Re: I smell a rat
If Charter agrees to this it forms a legal contract and can't be undone by a future administration. Yeah, it is only seven years, but that's takes us to the middle of the next decade. Who knows what the ISP landscape will look like then, maybe uncapped service will have become the norm.
They may bin the caps but throttle you during busy periods at a certain point, or find some other way around what they agree to. It is all about the wording, and big corporate lawyers are always better at leaving themselves wiggle room than the government is at anticipating their evasion.
