Modern Wi-Fi doesn't just give you fast browsing, it also imprints some of your finger movements – swipes, passwords and PINs – onto the radio signal.
A group of researchers from the Shanghai Jaio Tong University, the University of Massachusetts at Boston, and the University of South Florida have demonstrated that analysing the radio signal can reveal private information, using just one malicious Wi-Fi hotspot.
In this paper, published by the Association of Computing Machinery, they claim covert password snooping as high as 81.7 per cent, once their system has enough training samples.
It's an attack that wouldn't work if you had a primitive Wi-Fi setup with just one antenna, because it relies on the sophisticated beam-forming implemented in Multiple-Input, Multiple-Output (MIMO) antenna configurations.

It's been debunked so thoroughly that wikipedia still presents it as the leading theory, while also mentioning that other one you linked.
It might be because your links like certainty and only present the Telegraph Theory as as likely possibility, no more demonstrated by proof than the No-Jam one.
Do we have a case of Galileo vs earth-centrism, or a case of Republicans vs Global Warming? I don't know, and I just learnt something, but "debunked" to the point of "joking", this is not.
