[Yetanfou]

You don't need to add a disclaimer on Stallman having said bad things on a totally different subject to be allowed to mention him. People quote Mahatma Gandhi all the time without mentioning that is had some problematic views when it comes to black people, they quote MLK without adding something about his attitude towards women, etc. Stallman is no saint [1], neither are those who denunciate him. He said many things which ring true when it comes to data freedom and should be seen in that light, not in the light of his more disputable utterings. Cardinal Richelieu had it right when he stated that he'd find something to hang the most virtuous of men within reading 6 sentences written by him.
