Your link seems to prove otherwise. RMS is seen to leave the development of the projects he started alone, letting the developers decide everything. Sometimes, less than once per year, he chimes in for a totally non-technical part of the project (a stupid joke in the docs). But even then, the lead developers can have their way! It looks that the GNU maintainers have already full control. What else do you need? That RMS cannot even participate in the mailing lists? These are open, you can also write there.
