T-Mobile Uses Data Caps to Manipulate Competition Online, Undermine Net Neutrality

[Commentary] T-Mobile’s announcement that they will exempt a handful of music streaming services from their data cap is but the latest example of ISPs using data caps to undermine network neutrality.

T-Mobile now joins Comcast, AT&T, and AT&T again as an ISP that uses data caps as a pretext to manipulate how its users experience the Internet. Unlike other carriers, T-Mobile does not have a data cap with overage penalties. Instead, when users hit their cap they find their connection slowed significantly.

While this type of throttling is probably preferable to huge overage fees, it still exerts a strong influence on what types of services T-Mobile subscribers use online. This influence is strengthened enormously when certain apps or certain content is exempted from the cap -- a practice known as “zero rating.”

This type of gatekeeping interference by ISPs is exactly what net neutrality rules should be designed to prevent. Furthermore, T-Mobile’s announcement once again calls into question the purpose of data caps at all.
