Most WSJ articles are behind a paywall. It sees the tanker version relied on multiple inputs and had a control column cutoff.
Also it only made single adjustments to trim
I might have missed it but I don't seem to remember any mention of this previous system in this thread.

It was mentioned before - maybe in the ET thread. It's been discussed in AF circles primarily to confirm that the same issue couldn't lead to disastrous results with the KC-46. Below is a good link on the differences.
