Your own screenshots include the 7GB tethering limit and the distinction underneath unlimited that it's only unlimited on smartphones. And what gives them the right to say how you use your bandwidth is that you agreed to it. Again, why do you think people should A] expect to use a cellular network not designed for terabytes of traffic per user as if it were a terrestrial ISP, and B] be subject to zero consequences for violating the TOS they already agreed to? This whole thing is bollocks, but no one bothers to read anything and just assumes if a company is doing it then it must be a terrible practice. If someone actually tried to sue T-Mobile over this they'd be laughed out of court, because nothing they're doing is hidden or shady in this area of their contract.
I did not fail to notice their 7GB tethering limit, and if you read what I said I was talking about that fairly directly. I reject the notion that it is ok for them to stipulate that your bandwidth can only be used for your phone. And no, I did not agree to it, as I am no longer a T-Mobile post-paid customer. If I did hypothetically agree to it, I would have to read the fine print which essentially contradicts the big bold writing to know what I was agreeing to. "UNLIMITED, until we choose to limit it, and only for one device."
Like I said, as far as I am concerned it is literally none of their business what happens to data packets once they reach your phone. For them to be allowed to insist that you only forward a maximum of 7GB of those packets to another device is opening the door to some rather intrusive relationships between ISP's and their customers. I am not a lawyer or an expert on the net neutrality legislation, but I sincerely hope that this will be proven illegal.
As an aside, I am a T-Mobile prepaid customer. I don't even have any data on my plan, because I live in an area that the only way I get service is through my own DSL line via wifi. If I wanted to connect to a T-Mobile tower, I'd have to drive for about an hour.
