It was not a secret by the time the ET302 flight crashed. I knew how it was working with the failed AoA data and how it responded to the pilots from the preliminary report that was issued in, what, December? Months before ET302. I think that knowing a little about it was what made things worse for ET302 as the pilots seemed to pick some details and actions out-of-order and in the worst possible way, as if they recalled reading something about it once but were foggy on the details.
A critical piece I've never seen is the force required to hold the nose up through the progress of the accident flights and at what point the forces should have been high enough to demand attention to pitch trim.
