Apart from a very few, every accomplished technologist have started using Twitter and their followers to attack others. This is nothing but the witch hunt from medieval times done differently.
I have interacted with RMS in Emacs developer list, he has a strong opinion and nothing more, nothing less. He is not trying to create a mob and nor is he starting an upraising. If you have an opinion, voice it and leave it. Yes, I agree RMS needed a PR to tread the land mine ridden modern life.
Overall, it is sad to see RMS and his work getting trivialized for totally unrelated reasons.
