Why would a stealth aircraft require fly by wire?

Because it is shaped to be stealthy rather than to fly.

The C of G can and has been adjusted by adding ballast, made from spent
uranium to the front or back of an aircraft, providing that the aircraft
was designed conventionally as a stable one.

Its amount of stealth does not alter its ability to fly to any extent.

Have you looked at a stealth fighter?
it is angled because it was the only way to do it with the CAD they had when
it was designed.
It is more like a flying brick than a plane.
The stealth bomber is a much more refined design and flys much better than
the fighter.
The raptor is yet another step forwards.

Stealth is built into the airframe by careful use of angles and
attention to gaps between panels. The idea of stealth is to reduce the
aircraft's radar profile down to the size of a small number of birds and
to reduce the heat that comes from the engines. To some extent, this can
be done by sucking in more air than the engine requires and bypassing it
to shroud the jet exhaust plume heat. There are other ways though.

That said, there are
devices that can look at the sky and tell you what flew through it
earlier.

The stealth fighters are easy to track if you have a large number of
transmitters and a few well placed receivers. The angles are all computed to
stop stuff being reflected back to the transmitter with the assumption the
receiver is co-located. The bombers have better absorbing surfaces but you
can track them by monitoring the changes in the EM field as they pass over
transmitters.
