I'm no lawyer but I don't think the AGPL says you must use the same branding in a fork, in fact most hard forks tend to prefer changing it in my experience, as the original branding might be trademarked and so they can't legally use it themselves without permission, and/or they just want to distance themselves further from the parent.
