There is a need for snark. Claiming unlimited when it's not is ridiculous doublespeak. It's lying.

They need to stop doing this, it confuses non-technical people. Advertise the limit clearly. Make it a big number if they need to grab attention.

..but in this case, there isn't one. FTA:

No data caps, speed limits, or bill shock

It's pretty explicit to there being no artificially imposed limits of any kind.

It's often this way. Once they have the customers, they introduce the limit, as the GP pointed out: the infrastructure has limits. Once they hit them, unlimited will disappear just as always.

Which they are free to do, as long as they let the people who bought unlimited keep it. Even freaking Verizon understands this (though they are making it slightly more painful).

If you buy the unlimited plan, you have every expectation to continue using it. It's still a net positive.

As is claiming that HSPA+ is "4G". T-Mobile is not rolling out LTE until next year.

The GSM governing body sided wi T-Mobile on that dispute. "4G" has been and continues to be nothing more than marketing speak.
