Bluesky CEO Jay Graber Challenges Mark Zuckerberg with 'World Without Caesars' Shirt at SXSW

Graber's Latin T-shirt and comments highlight Bluesky's decentralized ethos as a contrast to Meta's centralized control.

Jay Graber, CEO of Bluesky, wore a shirt at SXSW reading 'Mundus sine caesaribus' ('A world without Caesars'), seen as a critique of centralized tech power.
The shirt design echoed Mark Zuckerberg's previous Latin-themed shirts, including one comparing himself to Julius Caesar.
Graber emphasized Bluesky's decentralized model, which allows users to fork or move to alternative applications if dissatisfied with the platform.
Bluesky, built on the open-source AT Protocol, has grown rapidly since its February 2024 launch, reaching over 33 million users by early 2025.
The platform positions itself as a user-first alternative to Meta's Threads and Elon Musk's X, gaining traction after political shifts in late 2024.
