@jjoelson @matthewstoller They don't. They don't because they are under no competitive pressure to do so. That's why there's an antitrust concern. It's not Mail per se. It's that they obviously have a lot of substandard products that nevertheless are widely used because default status + privileged integration make them more convenient for those in the ecosystem. Mail is unimportant (from DoJ perspective) in itself, but it's evidence the best app doesn't win under the rigged game Apple has made.
