I hate that term, because it isn't virtue signaling when one truly believes in the virtue.
I think that certain...techies on the autistic specturem who might not feel that virtue think that others are "faking virtue" when they're not and thus bring up the "virtue signaling" accusation.
Stallman's a guy who spent his young adulthood in a code-dungeon with other people just like him. And most of us know he's on the autistic spectrum. He's not the guy you want doing PR, he's the guy you keep behind the scenes and away from the people with the money you need. He's got away with being the PR person because OTHER autistic tech people have gone easy on him for obvious reasons. He's a man of his time...and well it is long past time he should retire from leading the FSF.
The FSF give him a nice stipend as chairman emeritus, and find someone more suited to the realities of modern computer use than somebody from the MIT AI lab priesthood who doesn't even use a computer in the modern way to understand the needs of modern computer users.
