I have no power over changing the default skin, but you can change the skin yourself; nothing's forcing you from using default. o_o
User CP > Edit Options > Scroll all the day down and you'll see a skin option.
OR
Scroll all the way to the bottom of any page. On the left you'll see a skin changer as well.
If you just think default should be changed, you can probably PM Hiroshi Sotomura and ask about it. *shrug*
