Apple makes profit fairly. Cellular companies charge people ridiculous amounts for almost nothing. Being a company that charges monthly they are accustomed to force people to pay ridiculously huge bills... You don't get this attitude from Apple. Can you imagine Tim Cook saying something like this? Apple things have gotten way cheaper over time as technology gets better. Why should carriers get to charge more and more because they get more use? The more use should give them more business and more money... It's the mindset... If you cannot see this then you have no place on this website.
Attitude wise you're right, but when it comes to the technical part you're wrong. I have a family member who is working with development of cell phone towers (not the towers per se, but the boxes that broadcast the signal) and sell them to the carriers who has explained it to me. I'll try to explain it as well as I can
First off, it doesn't get cheaper per unit, the more traffic your customers use, often it even gets more expensive. And considering how the usage is increasing faster than the users and that the technology is moving forward meaning you won't see a decrease in price as the years passes by.
Secondly, more and more badly coded apps are being released. With badly coded, the main issue is keeping the lines open. For instance, push e-mail works in a way that the phone doesn't have a constant line open, but opens up one when it receives a signal from the mail server. But apps like Word Feud keeps one open line per player. So if I play against ten people, I will use ten lines in the closest cell phone tower. Even though these lines are not sending or receiving, they are still occupied, and a cell phone tower only has a fixed number of lines to our (the clients') disposal.
Just imagine you have a thousand phones connected to a tower, each and every one playing ten people on Word Feud, and some of them are on the same tower (meaning they will use twice the lines). So a tower gets swamped, despite no one actually using any data, but the carrier is forced to update the hardware in order to ensure a decent quality (imagine living in a city and not getting any reception despite it being full of towers everywhere)... This costs money. Or, in the words of my family member, "I love these bad programmers, they make us rich".
It's no wonder most carriers are "artificial" (using a "real" carrier's network), considering the cost that goes into maintaining and upgrading a network these days...
But that being said, I have no idea how the prices at AT&T are and how they compare to their actual cost. Their previous engagements might actually be costing them a lot of money, or maybe he's just being a greedy little ****** that wants his already huge profit to be larger. I don't know. Just wanted to spread my knowledge of the carriers' present problem with cost of hardware...
