Or anyone else's. There is nothing Mavic does that isn't a standard process used by dozens of industries.

This layer has the following properties:

•enhanced rim rigidity
•reduction in friction generated heat
Do you work in Mavic's marketing department?
Your first point is of little consequence since brake wear rubs off the CD layer in short order and corrosion isn't a significant factor in rim life anyway.
The second claim is just not true. The CD layer has no significant contribution to rim rigidity. If anything the anodized layer is brittle and if it cracks it can act as a stress raiser and increase the tendency of the base metal to crack also.
Your third point is really a negative and FBinNY has disposed of it nicely.
