Surely this claim cannot apply to all humans who refer to that social media service. There are multiple potential competing explanations that have nothing to do with virtue signalling. For many, particularly non-users or rare users, “Twitter” is a more familiar name. Personally I don’t like the new name; and since it’s not a person, dead-naming it causes no one any harm or offence. Twitter, X - if one’s interlocutor understands that you’re both referring to the same service, what does it matter in casual circumstances?
