At least with radicle all the forks will still exist even if the authoritative copy is taken down. And even then I think because radicle is like BitTorrent, anybody who pinned the main repo would still be seeding it so it would be very hard to scrub it completely.

Otherwise there's no momentum and nobody will pin the countless mirrors published by randos.
