Honest question: what does T-Mobile think data actually is?

[Commentary] Here are two lines from T-Mobile’s latest "Uncarrier" missive, in which the company proclaims that it has "listened to customers" and is changing its new T-Mobile One plans less than two weeks after announcing them. The first line: "Everyone gets unlimited talk, unlimited text and unlimited high-speed 4G LTE smartphone data on the fastest LTE network in America." The second line: "With T-Mobile ONE, even video is unlimited at standard definition so you can stream all you want." At this point it appears that T-Mobile is operating with definitions of "unlimited" and "data" that are are only tangentially related to reality. For example, most people understand the word "unlimited" to mean "without any limits or restrictions," but T-Mobile’s definition clearly means "without any limits except for a hard restriction on HD video that can only be lifted for $3 a day or $25 a month."*
