This isn't really a problem, is it?

Henri is hosting this site without payment (as far as I know), so he's not losing any income with those ads, if anything, he's making money of them!

Besides, SL is built on KiXtart, and if you want to do anything outside the standard provided options, you still have to program in Kix...

It's just a marketing line, no harm done.

besides why would they have this on their site, if you don't need Kix at all?
