How does tangled solve that? Repository contents are still hosted by the forges themselves.

I was addressing the question of a use-case for a "federation of forges". Not any specific design or implementation.

		That sounds more like you want better decentralization, like IPFS or BitTorrent, not necessarily federation between different forge instances. I'm not familiar with any existing federated system that would be resilient to government censorship. Certainly Mastodon and Bluesky aren't.
