The issue though is your computer is always a server on the internet, so it never made any sense.
As long as you are not running a high traffic business website then no one is going to care.
I honestly think the real reason this is in most TOS is not just to limit network congestion but also limit angry phone calls. If someone hosted their business at home on a non business rated conenction and the service goes down they will be calling in complaining and crying about lost money.
