That's what it looks like to me as well but whenever this is asserted, GNOME folks are quick to point out that they are understaffed and GNOME is a community project. I suppose we'll never know the reality.

I remember reading on HN that SuSE has people for GNOME developement but no one for KDE development. IIRC, they also ship with GNOME as the default choice.

I've mentioned GNOME being similar to Android and Chromium in its nature of "look but don't touch" open source (unless you are part of their "community") but this hasn't been received well.
openSUSE has a KDE team, but I'm not sure to what extent they do upstream KDE development. [0] Also, openSUSE does not have a default desktop choice. I don't know where the enterprise offering differs from the community offering in these matters.
