I see his role a bit different - RMS stance on software freedom should be understood as a constitution. Setting in stone the ground rules that can then be amended, but not overturned.
Sure - current generations deal with a different reality compared to when he started out, but there is still paramount value in having his philosophy at heart. He may be old fashioned when it comes to new technology and he sure is quirky in a way that drives away some people, but all that doesn't stop people from interpreting what he has done and applying it to the world today.
I think the real problem is that you put RMS on a pedestal that he doesn't belong on. He is not the root node for what happens in Free Software today and I'm sure that the examples you cited weren't really that much about him, or even about the GPL3.
He has a very distinct, central viewpoint: freedom - and the link you quoted shows that you simply have a differing opinion about where to start thinking about software. You start with the user expecting features, RMS starts with the user deserving freedom. Both viewpoints have value, but RMS represents a constant that shouldn't be messed with and does not necessarily get in the way of your objective.
It is much more sensible to respect his service and do your best to live up to the standard he has set than to deconstruct his persona based on it being somewhat anachronistic. In my opinion, the best progress is made in dialog with our history, not in annoyed, knee-jerk revolt against it.
