Rare comparative W for American ISPs?

Not really, as US ISPs have been repeatedly trying to game the system into becoming landlords for decades. The difference is, ironically, their own self-imposed monopolies: Comcast may be a T1 ISP, but they’re largely a monopoly in the markets they serve. Same goes for Verizon, Spectrum, Cox, TDS, etc. The end result is a sort of “forced cooperation” with each other, though occasionally one will try to extort the others for cash (I seem to recall L3 and Cogent both engaging in this bullshit around the time streaming video got big).

Companies are extractive by nature, and they will always try to find new ways of squeezing blood from a stone absent regulations saying otherwise (and suitable punishments ensuring anyone caught violating them is crippled in the marketplace, if not outright destroyed). This has been going on for decades and will continue absent regulatory intervention. Just look at how the US Electrical grid bills to see how this could end up (higher prices, bullshit fees, redundant billing).

I think Comcast charges for peering as well (but not through an intermediary).
