Another shoot from the hip answer, but I don't think that's the issue.
They do some great things with magnesium. But, cost is very high.
That's the reason "mag wheels" are no longer made from magnesium
alloys, but from inferior aluminum alloys that weigh more and bend too
easily (bending being a solvable issue).

I think you need to combine this factor with the "trend" factor above.
Carbon fiber is in vogue. Oh, so trendy!
