It’s an e.V., a German legal construct for public good organizations.

That doesn’t make it impossible to buy it, but all profits from a sale must flow into recognized public good efforts. The incentive to sell for huge sums is just much lower for all people involved.

It is a non-profit association based in Berlin, and its very existence is a protest towards Microsoft and the other big actors in this space. And it is built on Forgejo, an open source project with a strong community around it.

Both Codeberg and sourcehut are good options when escaping the walled gardens of Big Tech :)
