@jjoelson @matthewstoller The antitrust case is not about any particular app. Apple does not have a monopoly over mail. It has tremendous market power, because it strives to make its platform sticky, not just by making it "insanely great", but by making it difficult and expensive to make choices that compete with it. It's not Mail's near monopoly that's the issue. It's that letting apps become crap without hemorrhaging users is exploitation of and evidence of market power.
