With costs of maintaining their networks flying through the roof, the nation's largest wireless carriers are attempting to limit the mobile Internet usage of their most download-happy customers. Mobile Internet usage is growing rapidly, and carriers are spending $50 billion a year to build new 4G networks that can keep up with customers' demands. That quote is disingenuous. The costs of maintaining their networks are not flying through the roof. The amount of people paying them a substantial monthly fee to use their data networks is what is flying through the roof. The amount of extra money being spent on network upgrades is not keeping pace with the rise in revenue from smartphone data plans. Yes, there is plenty of competition in the US wireless market. Which is why the remaining carriers are becoming more and more the same. This situation will only get worse when the FCC / DoJ inevitably approves the ATT/T-Mobile buyout.
