Yeah exactly. I imagine they could turn their current servers into relays and migrate existing Gab content onto the Nostr protocol.

Gab's relays could prioritize their own content, but still temporarily store content from other Nostr servers to help the protocol as a whole. And Gab users would have their content spread across multiple Nostr relays, so the whole Gab ecosystem is distributed and censorship-resistant without completely sacrificing the Gab community and identity.
