5d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.

I don’t get where do they come with the logos and branding. While it’s fair and just to give credit. I would understand this section as permission (if they were really mean about it) to leave any and all pages out of the fork and it wouldn’t bind them to even have any UI attributions, to anybody, but if they have something like about or license page then that should contain licenses and attributions? That is as long as the work has reasonable attributions somewhere. Or does the license limit modification in those parts of the UI code? I don’t think it does. I could be wrong.
