Bluesky quickly sold out of the t-shirt its CEO wore to troll Mark Zuckerberg

Bluesky CEO Jay Graber made headlines at SXSW by wearing a t-shirt with the Latin phrase 'Mundus sine Caesaribus' (a world without Caesars) aimed at Mark Zuckerberg. The t-shirt quickly sold out as Bluesky users rushed to buy it. This move reflects Bluesky's commitment to decentralized and open-source social media, emphasizing user and developer autonomy over corporate control.
