I don't think RH take away all rights to the ebooks though right? They just treat it like a variation of the print book, authors still receiving royalties from sales. Something most authors wouldn't be concerned about.
But the authors who don't like the percentage of ebook royalties they receive or are interested in getting their ebooks into some other distribution network and have those pre-1994 contracts appear to have the legal precedents well and truly on their side. From the consumer point of view that outcome 'might be' nice because it might mean authors can move their ebooks to platforms with less restrictive DRM and cheaper prices.
