It's a profit-driven adjustment to the status quo designed to fuck over consumers everywhere, and has us paying attention to all the wrong things when it comes to our data connections. It doesn't matter how fast it "can" be. It matters whether or not I can actually use it for what I bought it for---the bandwidth---without being billed to absurdity for using it.
I'll bust out the calculator:
- ((25 Mbps) * 1 month) / (1 gigabyte) = 8025.34
- 8025.34 GB * $10 per GB = $80253
Okay, so at the "standard" $10/GB rate, it's an amazingly affordable eighty thousand dollars per month to actually get what I thought I had for $50. Great. But that's LTE! Cellular is expensive because of spectrum/costs/blah blah blah. What about a wired line? I think that's $10 per 100 GB, or $802 per month. Gotta love DSL. It's cheap!
These usage fees are obviously outrageous when you look at them, and it's no different from the wholesale fleecing of the public that was SMS pricing until... well shit, the cellular companies still break it off in you for SMS. They don't let you pay for a limited quantity anymore. It's all or nothing.
