This paper explores the ways in which users give up as well as revert back to using social media based on the analysis of qualitative data from 680 respondents to a survey (N=1072). By focusing on the motivations rather than any particular social media platform, we were able to uncover reasons for voluntary non-use and reversion when users have a choice of several social media platforms. Our findings provide an ecological view of social media non-use and reversion highlighting that 1) previous findings of social media non-use and reversion reported on a single social media platform (e.g. Facebook, Twitter) are seen across several other platforms too; 2) access to multiple social media platforms in itself readily leads to non-use of one platform in favor of the use of another for reasons such as lack of differentiation and/or richness of features, device constraints of storage/ memory space or operating system support, perceptions of fading popularity, and availability of “a new kid on the block;” 3) findings of non-use and reversion practices and motivations that were seemingly incongruent between previous studies of different or same social media platforms tend to coalesce when we take a wider look at the social media landscape. By adopting the theoretical lens of cognitive biases in decision-making we were able to explain why users quit but decide to revert to using again in the environment of various positive and negative experiences on a particular platform, and to reconcile the seemingly paradoxical reasons for social media non-use and reversion.
