Your broad statement is ridiculous. I am not friends with 3 billions of people, but many people I care about are on the fediverse; everyone (within the margin of error) is on the fediverse. No one (within the margin of error) cares about a tech forum hosted by a VC (from https://whaly.io/posts/hacker-news-2021-retrospective). And yet here we are.

Please don't use only your tech and stats goggles to analyze the situation, understand that we are talking about people with a vast range of experiences and wants and needs.
