It's political. Bluesky is the "reasonable liberals" platform, to be distinguished from Mastodon's "woke liberals and furries" crowd. Nostr is not high-class enough, because it's a little too anti-authoritarian, whereas Bluesky and Gnome are both projects of academics, whose entire worldview is built around authority, starting with authority of their college.

What is omg Ubuntu?

people on ubuntu will be so much happier if they hackintosh their machine or go back to windows so they can use adobe and ms office again lol

It actually starts well with that "much-hyped open-source alternative". And that's been ... part of the issue for ages now. We're not that much talking Software Libre (or Libre) anymore, but merely "open source". A technical term devoid of any political or social concepts. Being socialized with copyleft as a mere "political" concept in the early 1990s, this still somehow gives me the creeps. 😔
