If Mark Zuckerberg’s new laid-back look—complete with shaggy hair and chunky gold chain—is any indication, he’s much different from the straightlaced, crew-cutted Apple (AAPL) CEO Tim Cook. It’s no wonder, then, that the business philosophies of Zuckerberg’s Meta (META) and Apple are as different as their two leaders. Zuckerberg has been eager to point out those differences and prod at a decades-long feud between the two tech giants and their chief executives.

While Meta has prioritized acting fast and engaging users, such as through its open-sourcing of its Llama AI model, Zuckerberg said in the Acquired podcast episode released Tuesday, Apple prefers maintaining a closed ecosystem of polished, exclusive products.

"I think in a lot of ways we're like the opposite of Apple," he said. "Clearly, their stuff has worked really well too. They take this approach that's like, 'We're going to take a long time, we're going to polish it, we're going to put it out,' and maybe for the stuff that they're doing that works, maybe that just fits with their culture."

Since Tim Cook took the helm of the tech behemoth, Apple has prided itself on being the best, rather than the first. For the most part, it’s worked out for the company, demonstrated by its superlative of the world's largest smartphone provider. Apple has long tended to its walled garden of in-house products, which has resulted in a uniform line of apps and accessories bespoke to its tech—and a whopping antitrust lawsuit from the Department of Justice.

But Zuckerberg touted Meta’s own spaghetti-at-the-wall approach to its products, which he believes has elicited helpful critiques and enabled the company to grow in spite of its failures.

"You want to really have a culture that values shipping and getting things out and getting feedback more than needing always to get great positive accolades from people when you put stuff out," he said.

There’s certainly been no shortage of feedback toward Meta, exemplified by social media platform Thread’s meteoric rise to 100 million users, only for the number of accounts to atrophy weeks later. Its flagship Metaverse was a $46.5 billion failure, but that still hasn’t stopped Zuckerberg from adding $58 billion to his net worth this year.

Apple’s perfectionism has been at its own expense, Zuckerberg said, arguing the company prioritizes praise above constructive feedback from users.

"If you want to wait until you get praised all the time,” he said, “you're missing a bunch of the time when you could've learned a bunch of useful stuff and then incorporated that into the next version you're going to ship.”
