It's actually a genius idea. If you are someone who the professional presentation of not having an anime girl on the loading page is required, then you can afford to fork over the cash to fund development.

I guess the disconnect here is a bunch of HN'ers believing professional companies and websites want to attach their branding to a sexualized anime character and that they are willing to pay to remove it.

Which one then wonders why they would install it in the first place.
