Your feeling that it was unbalanced is another example of the bias I'm talking about. Both sides over-weight the datapoints they dislike and under-weight (or simply don't notice) the ones they approve of, so both sides end up with a feeling of unjust imbalance. This is what I mean by false feelings of generality.

I did a cursory search for "RMS" and "Stallman" in the past month, since your link was posted. I found 3 pro-Stallman articles (and no anti-Stallman ones):

That brings our total to 16 negative and 11 positive, or 1.5 anti-Stallman articles per pro-Stallman articles. (60% anti-Stallman.)
