Stop comparing Mastodon and Threads/Bluesky. It's a category mistake.
These things are not apples and apples.
Mastodon is a grassroots alternative to the ugly silos of commercial social media. It offers baked-in interoperability, decentralization, cooperation and a future that isn’t based on enshittification.
Mastodon is everything Threads/Bluesky is not.
I’ve seen shiny-faced developers from Threads and Bluesky discussing how the future is federated and how they look forward to joining hands with everyone. They really seem sincere, but they are doomed.
