We have two cats and our name for this phenomenon is “other brother”. As in, each cat is convinced their brother has been replaced with a doppelganger that isn’t quite right. Hence, “other brother”.

I find the “digital commons” and the “online town square” metaphors to be poor ones when thinking about moderation on social networks. It’s shoehorning analog concepts onto digital information transmission systems. The two are not the same. Harassment and misinformation spread happen very differently digitally than they do in the analog world. “Digital commons” metaphors are prominent amongst “free speech” hardliners like Dorsey and Musk who simply don’t want to go through the hassle of developing, funding, and creating policy for online speech moderation. Anyone who uses phrases like digital commons loses a fair amount credibility in my eyes.
