I'm baffled as well, there is definitely no corrosion on the shafts. I have previously lifted the dust boots while the car is on a lift, and they look fine.

What is also perplexing, is not everyone is experiencing this problem. The reports seen few and far between...I have done a few internet searches and can't find a lot of posts on this issue.
