> Why bother with Mastodon interop? Why bother building on top of a standard that doesn’t do what you want if you don’t think being part of the “Fediverse” is particularly interesting or a goal of the platform you’re building?

Because they pretend to want to be open, and it's sending a very clear signal that is not their goal if they're not even trying to work with the existing ecosystem.

If they just want to be a silo, that's fine. But in that case be honest about it.

Er why are you conflating “being open” with “being part of the Fediverse”? The Fediverse has no monopoly on that notion, and in fact shaming folks for not wanting to integrate with it is the opposite of open. It’s like saying “BSDs pretend to be open, but they’re not even trying to be compatible with Linux”.

Making a conscious choice about differences is fine. The BSDs and Linux share many things, and not other, on the basis of different goals. They're not different for the sake of being different. The vibe I'm getting from the way AT is different is that they're different for the sake of being different.

The “Fediverse” is not an existing ecosystem in any way that replaces Twitter or builds an interesting social network, from my perspective at least.

No matter how open I wanted to be, if I was setting out to build a social network, I’d please precisely zero value on being connected to that “existing network”.

It is irrelevant to me, despite what a vocal minority might want me to believe.

It might not matter to you, but that doesn't mean it doesn't exist, and choosing to ignore it is a clear signal.
