I think I deeply disagree with this on a fundamental level: as I understand it, you think about decentralization as an engineering strong point, but as a product/UX problem. For me, what is important is the polar opposite: decentralization is key on a product level. I don't support the Fedi because I want a world with a single community-run social network. I support the Fedi because I want a world without any single social network with more than a few thousand uses. I don't want a new, better Twitter. I want an internet that's wild and truly decentralized again. You can't wild the internet by asking people to own their homes but then imposing an HOA that defines how those homes should look like. As Gabbo said, that's just the bluesky model. I don't want bluesky. I want weird platforms developed by a Peruvian teenager where you can't upload any picture that is not of a cat and have three dozen users being as first class Fedi citizens as the flagship mastodon instance. Actually, I want no flagship mastodon instance to exist as the flagship anything.
If we want people to change their mindset about what internet should be, we can't mold ourselves to what they already expect internet to be.
