The next AoIR 2013 plenary starts with Tarleton Gillespie, whose interest is in the politics of platforms. His initial thought was that users would be unaware of the issues related to platform politics, because of the seductive apparent openness and permissiveness of platforms like Facebook and Twitter. But this is no longer true - there has been a shift from complaints about policies by aggrieved users towards a subversive use of platform rules as a way to highlight their problematic nature, by increasingly politicised users.
In 2010, for example, Apple purged some 5,000 apps from its App Store for "unacceptable" content. These removals were contentions because the distinctions between acceptable and unacceptable nudity, political expression, or transgression against societal norms were far from clear; Apple pulled some "gay conversion" apps following complaints, for example, but there was nothing explicitly in Apple's rules which prohibited their content - they did not contain strong hate speech, for example, but in articulating their perspectives were seen to promote it.
