Richard Stallman spoke at Microsoft Research this week
Without sounding too sacrilegious, Dr. Stallman is the Free Software Jesus--he preaches the gospel of Free Software to the whole world and associates with "sinners" calling them to repentance.  If he can bring "the truth" of Free Software to Microsoft employees and help them "see the light", why wouldn't he?He certainly looks the part of Free Software prophet when dressed as Saint Ignuicius: https://stallman.org/saint.htmlHaving met him in person, he is extremely sincere about his beliefs and practices and really does "practice what he preaches".
