In his two decades running the company now known as Meta, Mark Zuckerberg has gone through many transformations. More recently, he’s been showing off a seemingly less filtered version of himself. But during a live streamed conversation with NVIDIA CEO Jensen Huang, the Meta CEO seemed to veer a little more off script than he intended.

The conversation began normally enough, with the two billionaire executives congratulating each other on their AI dominance. Zuckerberg made sure to talk up the company’s recent AI Studio announcement before settling into his usual talking points, which recently have included pointed criticism of Apple.

Zuckerberg then launched into a lengthy rant about his frustrations with “closed” ecosystems like Apple’s App Store. None of that is particularly new, as the Meta founder has been feuding with Apple for years. But then Zuckerberg, who is usually quite controlled in his public appearances, revealed just how frustrated he is, telling Huang that his reaction to being told “no” is “fuck that.”

“I mean, this is sort of selfish, but, you know, after building this company for awhile, one of my things for the next 10 or 15 years is like, I just want to make sure that we can build the fundamental technology that we’re going to be building social experiences on, because there just have been too many things that I’ve tried to build and then have just been told ‘nah you can’t really build that by the platform provider,’ that at some level I’m just like, ‘nah, fuck that,’” Zuckerberg said.

“There goes our broadcast opportunity,” Huang said. “Sorry,” Zuckerberg said. “Get me talking about closed platforms, and I get angry.”
