My ISP's a dick, but to my knowledge, unlimited has to mean unlimited around here. There where months where we had Problems with our fibre, so I did everything over a hotspot from my phone. Used 100's of GB's no one ever complained.
This is the case in a lot of countries. In Australia, some ISPs got fined a lot of money (something like $300,000 I think?) because they advertised mobile phone plans as "unlimited" when in reality they slowed down the speed once you hit a limit.
it's not especially in the US, i've seen ISPs essentially break kneecaps forcing the consume to pay for the initial hook up, and then immediately rolling it out to every available house in the subdivision or neighborhood.
That shit should be illegal. If you do the math on how long it would take to profit from running it yourself it's only a few years given an ENTIRE neighborhood.
The maximum ISPs could be fined for misleading/deceptive conduct (including things like this) was $1.1 million at the time, and I don't think they considered this bad enough to hand out the maximum fine. They bumped the maximum to $10 million at some point afterwards though.
Yeah. I mean, the state I live in right now just passed a bill to forbid officers of the state from using gender neutral, but technically grammatically incorrect language, while the ruling party is campaigning on not being a party of bans, while claiming their rivals are, so things aren't all that green here either.
