That article states over and over that they use EMG.

  Yeah - I wasn't disputing that. But this paragraph in the article is interesting and noteworthy: CTRL-Labs’ work is built on a technology known as differential electromyography, or EMG. The band’s inside is lined with electrodes, and while they’re touching my skin, they measure electrical pulses along the neurons in my arm. These superlong cells are transmitting orders from my brain to my muscles, so they’re signaling my intentions before I’ve moved or even when I don’t move at all. The point is that it's sensing neural signals, not physical gestures. So you're right that it's not a brain-computer interface in the sense that EEG is, but it is still arguably a brain-computer interface, given that what it's sensing is neural activity generated by brain. This question is discussed in the article: If CTRL-kit doesn’t directly connect to your brain, is it still a brain-computer interface? Reardon argues that the armband is giving people better versions of the same functions they’d get with a headset or implant, using the same kind of neural signals you’d find in the brain. CTRL-Labs obviously reaps some publicity benefits by using a hot technological buzzword, but by claiming the term, it’s also implicitly questioning whether “true” mass-market brain interfaces even make sense. It just seems that it's a matter of nuance and interpretation rather than being clear-cut.
