I don’t know where you got the suggestion of sainthood. I personally am not a communist-adjacent like he is and believe me I cringed when I typed the term “oppressed.”
The point is that most people, even most new hackers, misunderstand who Stallman is and what his principles are. At best they see him and some random crazy pedant that’s probably never wrote a line of code like most politicians or lawyers in his space. They don’t understand the dude wrote the world’s most popular compiler for three decades or more (I won’t be surprised to hear they think BillG is more technical than him if you survey). Nor do they have a grasp of his movement to the degree they attribute Open Source, a deliberate and successful attempt to derail his PoV, to himself!
None of that implies sainthood or value judgement on him. It stops at hearing what the guy really says carefully.
