Something I don't think is mentioned here is that initially the Boeing designers thought that both sensors were being used for the data but the code written only took it off a single sensor. Whether it was not properly communicated to the coders or what, it is not clear, but someone at Boeing had wanted multiple sensors. (I don't remember the exact source, I'd written a report of the Max-8 crashes and this was part of what I found. If you're interested in a generally excellent source for the accident/design flaws, the (latter) US Department of Transport report is excellent. I can also share my work if someone is curious, though its quality and depth is of course much lesser.)
