Debian is not a commercial entity. It's a volunteer organization.
In fact there's been quite a bit of vitriol about Canonical (company behind Ubuntu) profiting (for what that's worth) from all the hard work from Debian volunteers and not sharing as much of that value back to Debian as was felt was deserved.
I've always wondered about that, I feel like ubuntu sometimes doesn't contribute fixes upstream. When I hear 'it works on ubuntu but not on distro X', it makes me wonder why ubuntu devs didnt post the fixes upstream.
* I do realise that different release timings can fudge with the timing, but when fedora is building upstream versions and I hear it, its a bit.. disheartening.
