Mickens came in with an agenda — he decided to “Examine whether the friction that Android imposes on non-Google Play Store app installation is justified by security concerns.”
His conclusions, as presented to the jury:
Conclusion 1: “The friction imposed by an operating system during app installation should be proportional to the likelihood that the app is harmful (as determined by a high-quality security review)
Conclusion 2: The friction that Google imposes to installing apps via third-party channels is unwarranted and disproportionate to the security risks posed
Conclusion 3: By making small changes to Android, Google could reduce the unwarranted friction while preserving (or even strengthening) the status quo of security on Android today
