Imagine thinking it’s bad to signal virtue.
It’s not censorship when the author is the one limiting who can see it. And what’s your basis for saying these people are the first to cry about internet censorship? Have you actually seen the same people doing this or are you just imagining it to be true?
Virtue signaling is not the same as being virtuous. It's an empty, zero effort, gesture that contributes nothing of real value or meaning. Like changing your profile picture or posting a trending hashtag.
Neither of those things are bad.
