The worker cooperative states:

We’re excited to announce NorthSky Social Cooperative where we are building a new ATproto platform for the benefit of marginalized communities that prioritizes the 2SLGBTQIA+ community. After increasing hostility toward these communities we are taking action to provide a platform built by and for us.

They go on to say:

A shift towards federation has enabled the survival of marginalized communities and @bsky.app which developed the AT Protocol has created a foundation for us to build Northsky Social on top of. As such we will be fully compatible with @bsky.app where users will be able to communicate across the federated ATproto space.
