"the Foundation will coordinate releases of GNOME and determine which projects are part of GNOME. The Foundation will act as an official voice for the GNOME project, providing a means of communication with the press and with commercial and noncommercial organizations interested in GNOME software. The foundation may produce educational materials and documentation to help the public learn about GNOME software. In addition, it may sponsor GNOME-related technical conferences, and represent GNOME at relevant conferences sponsored by others, help create technical standards for the project and promote the use and development of GNOME software."
That sounds like an AWFUL lot of power to me, if properly used.
