Hypothetically it hurts the "two guys in a garage" who have to hire a third guy (or pay a middleman Turbo Distribution Network) just to handle dozens of ISP turbo contracts.
How does it hurt them compared to the baseline where it's not even an option - the standard 5Mbps is all the customers have, and if garage-guys-service benefits from bursts of more speed, neither the customer nor the service can easily pay the few dimes it might cost?
Or the baseline where, because there's no revenue from 'turbo', a freemium broadband tier isn't offered at all, leaving customers without even the free 5Mbps, or (having paid for broadband instead) with less budget for garage-guys services?
(Also, if such a upsell were available, from Google or others, it'd not necessarily require bilateral contracts. It could and should be an automated service, discoverable in a standard way.)
