Stallman has done a great service to OSS. However his personality and stances might be detrimental. I happened to meet him around 12 years back and that meeting turned me away from associating with anything which he is involved. I was helping organize the biggest software event in India and as a part of that we had invited him to speak. I was responsible for his arrangements and he was very rude to me throughout. He kept making fun of me because of my accent (which apparently was sufficient to get a leadership role in US at one of the Fortune 15 companies). Needless to say it was very childish and a complete turnoff.
