I think your view on that mentioned flight could well be called somehow superficially, but I intend no offense here.
Wikipedia might help a bit, but the picture stays diffuse http://en.wikipedia.org/wiki/Air_France_Flight_296 so no clear "Pilot!" or "machine!" can be spoken in my eyes.
Seems like a sad roule in such cases, on thing out of many leads to another one, building a chain one has to break. Sometimes nobody does. And even experienced pilots get upset and forget to slam the throttles to the top end of the range if they want to enable TOGA. If engines then fail, the only law that comes to my mind would be Murphy's then.

But you've mentioned the Hudson River "landing" (USAir1549). From my point of view, this is a big pro for Airbus there since the thing proved to be able to let a good Captain land, even on water. So maybe I don't get the point your were stating.
Bird strike can't be prevented by FbW.

The question of good or bad in case of the Fly by Wire stuff is somehow obsolete though but I still am interested in opinions here. The stuff is there, since decades, and is used every second as we're typing.
Even the law based operation is very common, not only at the Airbus planes. So if there was a proof of a system not being able to maintain safety throughout a huge envelope, it just wouldn't get installed, despite all emotions towards chips and electric cables. CFIT (Controlled flight into terrain) for example can (and did) happen with or without electronics, it just takes a weak link in the chain.
