Platform privacies: Governance, collaboration, and the different meanings of “privacy” in iOS and Android development

Abstract

Mobile application design can have a tremendous impact on consumer privacy. But how do mobile developers learn what constitutes privacy? We analyze discussions about privacy on two major developer forums: one for iOS and one for Android. We find that the different platforms produce markedly different definitions of privacy. For iOS developers, Apple is a gatekeeper, controlling market access. The meaning of “privacy” shifts as developers try to interpret Apple’s policy guidance. For Android developers, Google is one data-collecting adversary among many. Privacy becomes a set of defensive features through which developers respond to a data-driven economy’s unequal distribution of power. By focusing on the development cultures arising from each platform, we highlight the power differentials inherent in “privacy by design” approaches, illustrating the role of platforms not only as intermediaries for privacy-sensitive content but also as regulators who help define what privacy is and how it works.

Better, Nicer, Clearer, Fairer: A Critical Assessment of the Movement for Ethical Artificial Intelligence and Machine Learning

“…This code eventually encompassed decision-making or analytical processes that implicitly or explicitly required expert knowledge, and birthed several subcodes used to distinguish sub-categories of expertise (e.g., 'technical' or 'legal'). Informed by prior discourse analyses of digital researchers [58] and technologists [59], the other authors collated and reviewed a set of shared themes and noted divergences, with reference to the sample and the prior stage's codes. Some divergences prompted a return to first-order coding, to ensure similar phenomena were coded similarly.…”

Engineering Privacy by Design: Are engineers ready to live up to the challenge?

“…I think it's essential" (Fleischmann, Wallace, and Grimes 2010, 3). Similarly, Greene and Shilton (2018) found that an "ethic of care" for users is common among app developers. They concluded that developer forums such as the iPhoneDevSDK forum and the Android XDA forums act as quasi-regulators, setting privacy expectations for applications to be published on their platform stores and thereby guiding app developers' privacy efforts.…”

Governing online platforms: From contested to cooperative responsibility

“…Recently, the United States' Federal Trade Commission (FTC) has sought to enhance mobile data protection through 'privacy by design.' Here developers are being encouraged to proactively implement best-practice privacy features to protect sensitive data (Greene and Shilton 2017). They effectively become 'ethical agents', expected to take responsibility for the privacy implications of their technical design decisions (Greene and Shilton 2017).…”
