Monetarization and politics aside, he got some valid points surrounding usability, ease of use and content.
The majority of the fediverse project's fail at onboarding user with simplicity. Modern third party clients (mastodon, pixelfeld, lemmy aswell) do that better, even par excellence. But if we keep referring people to websites with server lists, we'll lose them at that point already.
Federation and lengthy explanations (wall of texts) and tutorials (sorry @[email protected]) are no selling-point for everybody. It caters the nerd in us, but average joe is not a nerd but a simple user with little interest for these details. You could better refer them to an App that works without account and say: hit the explore button to see communities/contents/hashtags (what ever drives the particular network). In my opinion the old principle KISS (keep it stupid simple) is what needs to be followed, so we cann pull people in.
