This paper examines the rise of the social media platform Bluesky following Elon Musk’s acquisition of X and the 2024 U.S. presidential election, which triggered the largest exodus in the platform” history. To understand this transformation in the social media landscape, I first analyze Gab’s emergence in 2017 as a case study in how alternative technology platforms develop in response to perceived political censorship and content moderation. Drawing parallels between these platforms’ trajectories, I argue that Bluesky’s growth requires us to fundamentally redefine our understanding of “alt-tech” beyond its traditional association with right-wing platforms. Through analysis of platform architecture, user demographics, and key events, I demonstrate how Bluesky’s development, like Gab’s before it, reflects broader tensions in the digital space. By expanding our conception of alt-tech to include progressive platforms emerging in response to perceived right-wing capture of digital spaces, this research suggests that Bluesky’s emergence marks a fundamental shift in our understanding of Big Tech, alternative platforms, and the possibility of maintaining ideologically diverse digital spaces.
