The 777 and 787 before it are true fly-by-wire designs like the Airbus in question here; the 737 MAX isn't and never was. It just had a computer that was supposed to add artificial inputs under a very specific condition, so it could continue to fly like the older models under the same type certificate and not require extra pilot training. It turns out that the condition could be triggered erroneously, and the logic to determine the artificial inputs was deeply flawed.

The 737NG already had computer controlled feedback to the control columns, the MAX added computer controlled spoiler deployment (like the 757 and 767) and elevator trim.
