Given that they claimed "Unlimited" bandwidth, I would say that you already paid for that slice of bandwidth you're using for your computer.
That said, it would be nice to have explicit limits at different price points, regardless of how you're using it. They don't seem to be doing this, though, even on AT&T where you're specifically paying for a given amount of bandwidth. You have to pay again.
I haven't signed up for a plan that claimed unlimited since the 90s. Maybe organizations around here are just more rational?
However I do have a 5GB plan on my smartphone. In an average month I use around 500MB, because there's only so much you can do on a smartphone, and they know it, but they monitor the curve and provide enough excess that I know that if I really needed it for a period, I could use it. They also sell data sticks for PCs, and they charge much more for lower caps, because of course they know that you'll use it.
My gym membership costs something like $19 a month. Technically I could go every open minute of every day, hogging equipment and space. So could everyone else. Of course then the gym could host a membership count in the dozens instead of in the many hundreds, and my real cost would be significantly higher.

So, parent was hyperbolic, but not bullshit.
