Glenn Fleishman:

With Mastodon, you’re not dealing with a giant, faceless company — or a constantly in-your-face CEO — making arbitrary decisions that are often impossible to understand or appeal. Instead, you join a Mastodon server — called an

instance

— run by an individual, company, or organization.

An individual, company, or organization equally free to make arbitrary decisions that are often impossible to understand or appeal. In a related article Fleishman writes,

Each Fediverse instance is its own Little Prince world that can choose to engage with other servers through federation, the interchange of information stored locally with other servers remotely. There’s no one in charge and no single place to go for definitive truth about the network.

“There’s no one in charge” on Mastodon-as-such, because Mastodon-as-such is just some open-source software, but there is very definitely someone in charge on any instance you join, and whoever that is can ban you any time for any reason or none. You can only escape that by creating your own instance of Mastodon, which possibly 0.01% of its users have the chops and resources to do.

Mastodon has certain virtues, at least for some, but let’s not attribute to it powers it does not have. In almost every respect Mastodon functions precisely as Twitter did, with, as I have said before, every single one of Twitter’s perverse incentives. And if you’re not running your own instance you’re not one whit less vulnerable than you were in Elon World.

People who are tempted by Mastodon should at least consider this from Luke: “I’m on Mastodon, but I’m bored of what I call ‘the timeline era.’ Scanning an unending stream of disconnected posts for topics of interest is no longer fun, I prefer deciding what to read based on titles, or topic-based discussion.” There are more things on the internet, Horatio, than are dreamt of in your timeline. And off the internet: far, far more.
