Quarterly reports are the stuff of business. In most people's minds, they are as far from the spirit of free and open source software (FOSS) as anyone can imagine. All the same, as non-profit organizations, many FOSS projects issue them.

The short answer here is that GNOME seems to have more corporate sponsors, while KDE is propped up by individual donations.
And lucky for us, both appear to be doing fine...
