You're not incorrect, but I think the thing that differentiates this era of social media from the "before times" (I was there too) is that it's significantly easier for non-techies to join. The internet nowadays has significantly more diversity of perspectives than back then. Those differences are exploited and exaggerated by social media companies to generate engagement. It seems to m that the fediverse model allows for diversity and sanity (or at least not algorithmically-encouraged _in_sanity).
