Surely the remedy to most Airbus crashes (Paris Airshow, XL888t, AF447...) is for the Pilot to use the Pitch Trim Control manually.
However this is the last control the plane wants the pilot to touch, it is imbedded under several layers of FBW technology. It is even painted Black and White, and will take your fingers off, like a circular saw, if you get too close to it.
There are only a few aircraft with Anhedral wings that actually need FBW to fly, all others have Dihedral wings, C of G, Centre of Pressure, and inbuilt stability in their airframes.
