Honest question, because from the outside he seems like an absolute grognard whose computing habits are so far removed from those of everyone else that he is incapable of relating to how the modern world does its computing.
Perhaps if he wants a good git interface in emacs, RMS should sling some code instead of giving the same entry-level ethics talk ad nauseam.
Why would that even matter? I find this attitude very puzzling and extremely worrying.
Of all the arbitrary metrics to decide whether to listen to and consider somebody's position "lines of code written" seems like an exceptionally poor choice.
I find your comment to be a good example of what is wrong in circles that like to consider themselves part of hacker culture.
RMS' opinion is taken very seriously in emacs development community.
