Your definition of non-negligible is my definition of insignificant or irrelevant.
I'm still on X, and despite the people I follow declaring they're leaving, it's still the place to be. They all still post.
> Why? Don't give me arguments based on circumstances.
You're the one claiming it's an improvement, the onus is on you to convince me why it's an improved experience. That said, I'm happy to give you my perspective.
Centralised services collect and colocate the information. If I follow the mavericks, i likelt want to be kept up to date with other stuff going with the NBA. Twitter, Instagram, tiktok do that in a way that hundreds of millions of people find valuable. If I want a source of news owned by mavericks, I can visit their website already. That exists, right now, for me to go and look at.
There's the question of "which mark Cuban" - is markcuban@mavs the right one, or markcuban@nba or markcuban@cuban (which has no affiliation to either the NBA, Mark Cuban or the mavericks). X has this (well, it had it and then fucked it), tiktok has this, threads has this solved. If I go and register markcuban@threads, and start posting impersonating mark Cuban, meta will step in (I imagine). You may not want that, but he does, meta does, and millions of people who use their services do.
For services like YouTube, they provide an Audience for NBA fans to show similar content to - you think the NBA doesn't want to get eyeballs from people who are interested in NFL?
And lastly, this is the nail in the coffin:
> The apps can be improved and content discovery mechanisms can be implemented. What is "fundamentally worse" about federated social media?
The fact that the apps are worse and the content discovery mechanisms aren't implemented. That's the magic and value in social media. You get it right, you win (see tiktok). You tweak it and get it wrong, people leave (see Facebook). You don't have it? People stay where they are, because I want to see videos of pandas, otters and frogs with knitted sweaters even though I didn't know I wanted the latter until I saw it.
