I read about it once and thought why couldn't I give back at least as much, even without religious justification. Perhaps ironically in this context, part of the amount goes to my local atheist charity.
Well, Ubuntu pioneered this thing! Fortunately it was short lived and you could opt out.
A good and user-friendly distro nevertheless. Who knows if it will ever "win" on the desktop, but I am sure the more mainstream it becomes, the more hate it will get!
