For the longest time the Android community was super close-knit where people talked about this stuff online and in person constantly, and OP was a pretty active contributor.
Unfortunately Twitter pre-acquisition was probably the focal point and since then, I don't think the community has been the same.
An interesting feature of ribbon mics - because the ribbon is open at the front and the back, they reject sound from the side (and top/bottom) almost perfectly. You can arrange these cleverly in live or studio settings to amplify one thing while rejecting another completely.
A typical usecase for this is a singer with an acoustic guitar - one mic can pick up the guitar and almost fully reject the vocals, and vice-versa. Pretty cool.
One thing that I found super interesting when I studied audio engineering is that our ears are very good at determining direction left/right, but absolutely hopeless at working out if a sound is up or down.
This makes their hypothesis a lot more believable to me; I can understand others incredulity.
