Bluesky’s Biggest Moneymaker? Ripping on Mark Zuckerberg

Last year, Mark Zuckerberg showed up to an event with a T-shirt reading: “Aut Zuck aut nihil.” This is essentially Latin for “Zuck or nothing,” and is a reference to the infamous Latin phrase “Aut Caesar aut nihil.” In other words, Zuckerberg compared himself to Julius Ceasar.

Bluesky, a fast-growing platform in the creator space, had its own fun with Zuck’s quip, with CEO Jay Graber showing up to SXSW with a shirt reading “Mundus sine Caesaribus,” which translates into “a world without Ceasars.”

Bluesky’s Roman Empire

After the positive reception to the joke, Bluesky decided to sell the t-shirt on its Shopify — and it almost immediately sold out.

The shirt was such a success, it’s already got a second print run, as Bluesky COO Rose Wang reveals that Bluesky earned more money selling t-shirts than it has selling custom domains for the past two years.

“That’s it,” she joked. “Pivoting to a t-shirt company.”

That’s it. Pivoting to a tshirt company… had more money coming in today than we did the last two years selling custom domains

During SXSW (per Mashable), Graber made another thinly veiled jab at Zuckerberg. “If a billionaire tried to ruin things, users could just leave [Bluesky] — without losing their identity or data.”

Created in the wake of X’s controversial takeover, Blue Sky has surged to over 32 million users. As anti-billionaire sentiment continues to resonate, this number is poised to increase significantly.
