This is not only the age of 'fake news', but more importantly the age of people publishing things, be it in the media, or 'just' on a forum somewhere on the internet, without knowing what they are talking about or doing a minimum amount of research beforehand. Thats why I wrote a few posts ago that all this talk about the 'shocking revelation' that Boeing is 'withholding information' about MCAS is absolutely silly - especially since we still don't know what happened to this particular plane.
Note that the "condition - continuously' in the procedure does not describe the MCAS behavior in the (postulated) faulty AOA sensor condition since it works in 10 second (max) bursts with 5 second pauses.
Totally true that following this will remove MCAS trim inputs, if the condition was recognized.
As others have pointed out until the Boeing/FAA missives the existence of this feature was not known to operators or line pilots.
