>But HN members who aren't mass-marketing could change that, by moving to the Fediverse -- giving it their endorsement, and network effects.
Why? Why should HN members, or anyone else, move to another network with the same kinds of fragmentation and mutual mass bannings (and/or demands for mass bannings) that we are talking about here with Bluesky? See, for example, <https://news.ycombinator.com/item?id=34748195>
Because with mastodon, you can just run your own server, and continue using the network.
Between my single-user-instance and Facebook's billion-user Threads, ActivityPub is genuinely decentralised.
The irony of that example is that it is not the same as BlueSky here. There were huge parts of the FediVerse entirely untouched by what happened at Mastodon.LOL .
