I don't think it turned out to be accurate. Ereaders haven't changed that much since then in terms of players and dominance. Apple's only move since then was to collude with publishers (for which they were given a light tap on the wrist) but which ended up damaging the pricing model and making ebook purchase worse for everyone in general. So they did attempt to solve it by first creating a different problem.
