@jjoelson @matthewstoller Apple does not prevent 3rd parties from releasing great mail apps. A few suffer and try. It's just mail apps are a dead market, because 90%+ of users rely on platform defaults or mail-provider web or mobile apps. Apple knows this. The reason it doesn't invest in mail isn't because it's trying against hope to help out Spark or Edison or Airmail. Mail is what Mac users use, if they're not at gmail.com. It doesn't pay to bother making it great.

@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.
