Threads is All The Worst Parts of Twitter And Instagram in One Very Bad App

But Mastodon is built on a technology stack almost as old as Twitter’s, and has largely failed to achieve widespread adoption despite several mass-exoduses from Twitter. BlueSky is more promising, using a brand new protocol called AT which promises to let users not only create their own instances of the service, but filter their feeds with custom algorithms, instead of settling for one centrally-controlled “master algorithm” that prioritizes engagement above all else.

• A new protocol that's not a standard being adopted elsewhere, is not promising, it's just another protocol. AT protocol is MIT license, but it's not a standard, ActivityPub is W3C standard.
• Also isn't creating own instances, something that's common in fediverse, while, is there any other AT protocol instances that's not owned by Bluesky?
• And isn't Bluesky a spinoff from original Twitter? What does she mean by old technology stack? LAMP? Mastodon is built on React, Redux, Ruby on Rails, NodeJS, and Postgres. I can't find any info about BlueSky's server stack, but it seems like their frontend is using React, and maybe Go.

Am I fucking crazy, or do people just pluck information out of thin air, without any fact checking and call themselves senior journalists? Does she hold any investment in Bluesky?
