Apparently,

The fediverse is a decentralized network of social media platforms that are able to communicate with each other.

Threads, Facebook, Instagram, Mastadon and Bluesky are apart of the fediverse.

So, your posts on these networks can be shared on all of the social media sites if you’re opt in.
