I'm guessing it has to do with the chemical makeup of the plastic and
that maybe sunlight and heat accelerate it. I've noticed that the problem
isn't just with CoCo's...seems to be with lots of white plastic products.
Some hold their color just fine, some do not. I HATE the yellowing as I'm
sure most do.
I haven't used any of the methods to whiten as I'd be concerned about
further degrading the plastic. I'd rather have a functional case, than one
that gets brittle and eventual cracks, chips, breaks or
crumbles.
What would be nice, would be to have some way to have a
new case available that doesn't yellow but looks like the original. Maybe
3D printing at some point. But I certainly wouldn't pay a lot just to have
a white shiny case.
