Fly-by-wire is not about airframe stability. High-performance jets are fly-by-wire because high-performance generally means you need to build an unstable airframe, and computer control is the only way to compensate for it.

But that's not commerical aviation - that's combat aviation. That's "you fly faster or the missile catches you and you die anyway" aviation.

Building intentionally unstable airframes for civilian aviation is a very different proposition. And unrelated to the use of fly-by-wire.
