Update: Blueskys Zuckerberg-trolling world without Caesars shirt is back in stock
The social media platform Bluesky made a limited run of the shirt its CEO wore at SXSW, which called out Facebook founder Mark Zuckerberg. After selling out its first run, it's now back in stock.
UPDATE: Mar. 18, 2025, 4:00 p.m. EDT Bluesky has restocked its "A WORLD WITHOUT CAESARS" shirt in sizes small through XXL. Shoppers need to place an order within seven days, the company said. Our original story follows.
It was the T-shirt heard around the World Wide Web.
Bluesky CEO Jay Graber made headlines this week for taking the stage at Austin's SXSW wearing an oversized black tee. But it wasn't just any Hanes or Uniqlo basic: The shirt was screenprinted with the phrase "Mundus sine caesaribus," which is Latin for "a world without Caesars" — a clear dig at Meta CEO Mark Zuckerberg, who infamously wore a similar shirt referencing a Roman ruler at the company's developer conference last year.
The shirt was a hit with Bluesky users (and Mashable readers). So on Thursday afternoon, Bluesky made Graber's shirt available for purchase for $40 at worldwithoutcaesars.com, with all proceeds going towards the AT Protocol, the open standard its social network is build upon. The shirt sold out in 30 minutes, according to Emily Liu, Bluesky's head of special projects.
Liu told Mashable that the company isn't sure if it will restock the shirt just yet. We'll update this story if another drop is ever announced.
Graber's shirt was a near copy of the one Zuckerberg donned for Meta Connect 2024 — same design, same typeface, but very different message. The Facebook founder's original shirt read "Aut Zuck aut nihil" ("Zuck or nothing"), a spin on the Latin phrase “Aut Caesar aut nihil” (“Either Caesar or nothing"). Zuckerberg has seemingly spent several years chasing an obsession with the Roman emperor Augustus Caesar.
