The trademark owner of course, because they are the only one with the legal ability to do anything about it.

Not knowing the technical details behind this, I can only assume it's because Red Hat has put in the work to cleanly separate their trademarks from the rest of their packaging. If you want to help Ubuntu do the same, you know how to create a spec for the work and how to propose it as a session during the Ubuntu Online Summit.
