Why are residential proxy providers charging per GB?

I've been astonished to see how much residential proxy providers charge for their services (and how little they pay the actual people providing the proxies).

The thing that I cannot wrap my head around is why they are charging per GB when bandwidth (especially residential) is basically free. Internet traffic is basically free at the margin for a household (as long as it doesn't exceed a huge amount) so why charge per GB?
