And that is just bandwidth (speed). You get to reach a cap earlier in the month.
Indeed, that's just bandwidth. Last I checked, the cap was 250 gigs which I tried to hit a few months ago and ended at using about 175... and I tried hard but I live alone.
When margins are 90%, who cares about caps? Give your customers a pipe, let them put as much through it as they want, take your high operating margins and laugh all the way to the bank. Let the content providers fend for themselves.
For most providers, the cap is really just to ensure it is only being used for residential use. I'm sure a household could hit the cap if they tried hard enough but the major intent here is to make sure its not being used for commercial use under residential costs.
