The negative use of the term "virtue signalling" honestly baffles me. Why on earth is publicly stating your beliefs is a bad thing? Communication is how ideas spread.
“Virtue signalling” refers specifically to a public performative show of caring not because a person/organization actually cares but wants some sort of social, financial, political, or personal benefit from giving off the appearance of caring.
Seems like to claim "Virtue Signaling" you have a.) "show of caring" but no evidence of b.) "wanting some benefit from giving the appearance".
And without any attempt of evidence or justification for claim of B, just dropping the accusation of virtual signaling comes across as merely trying to describe "openly not being an asshole" as if it were a bad thing.
How do we know the person behind the Rust twitter account doesn’t actually care? Because that’s the clear implication in labelling them a virtue signaller.
