From what I deciphered, the actual suggested cause was "aeolian vibrations" [0], which is one of the three forms of wind-induced conductor vibrations according to this [1] IEEE article. Also known as "flutter" according to Wikipedia [2]. (I'm not in EE so can't confirm nor debunk.)
Connected to this, another seemingly made-up term that made the news cycle was "Ging-induced vibrations" (in Portuguese media). Now, I don't speak Portuguese, but all my efforts hunting down this mysterious Ging tremendously failed. However, when I plopped ging into translation models, I couldn't help but notice that "ginga" in Portuguese means "swing", as in cable swing. So I'm giving it pretty reasonable chances that "ging" (no capitalization) might be what "flutter" is in English, i.e. the industry slang for "aeolian vibrations" there. And then the rest was just a typical journo move, much in the way of "the hacker known as 4chan".
In any case, it would have been cool if anyone actually linked to where said company made their statement, so that people could independently verify what was actually being said. From what I read, they have since explicitly debunked that they were inventing any new niche atmospheric effects. It's incredibly disheartening that such basic bits of information can become this seriously distorted before going viral, even (especially?) in this day and age. Makes you wonder how trustworthy are the regular news, even biases nonwithstanding, that aren't so readily obvious to be bollocks.
