The New York Times reports:

When Tim Cook and Sundar Pichai, the chief executives of Apple and Google, were photographed eating dinner together in 2017 at an upscale Vietnamese restaurant called Tamarine, the picture set off a tabloid-worthy frenzy about the relationship between the two most powerful companies in Silicon Valley.

As the two men sipped red wine at a window table inside the restaurant in Palo Alto, their companies were in tense negotiations to renew one of the most lucrative business deals in history: an agreement to feature Google’s search engine as the preselected choice on Apple’s iPhone and other devices. The updated deal was worth billions of dollars to both companies and cemented their status at the top of the tech industry’s pecking order.

Now, the partnership is in jeopardy. Last Tuesday, the Justice Department filed a landmark lawsuit against Google — the U.S. government’s biggest antitrust case in two decades — and homed in on the alliance as a prime example of what prosecutors say are the company’s illegal tactics to protect its monopoly and choke off competition in web search.

The scrutiny of the pact, which was first inked 15 years ago and has rarely been discussed by either company, has highlighted the special relationship between Silicon Valley’s two most valuable companies — an unlikely union of rivals that regulators say is unfairly preventing smaller companies from flourishing.

“We have this sort of strange term in Silicon Valley: co-opetition,” said Bruce Sewell, Apple’s general counsel from 2009 to 2017. “You have brutal competition, but at the same time, you have necessary cooperation.”

Apple and Google are joined at the hip even though Mr. Cook has said internet advertising, Google’s bread and butter, engages in “surveillance” of consumers and even though Steve Jobs, Apple’s co-founder, once promised “thermonuclear war” on his Silicon Valley neighbor when he learned it was working on a rival to the iPhone.

Apple and Google’s parent company, Alphabet, worth more than $3 trillion combined, do compete on plenty of fronts, like smartphones, digital maps and laptops. But they also know how to make nice when it suits their interests. And few deals have been nicer to both sides of the table than the iPhone search deal.

Nearly half of Google’s search traffic now comes from Apple devices, according to the Justice Department, and the prospect of losing the Apple deal has been described as a “code red” scenario inside the company. When iPhone users search on Google, they see the search ads that drive Google’s business. They can also find their way to other Google products, like YouTube.

A former Google executive, who asked not to be identified because he was not permitted to talk about the deal, said the prospect of losing Apple’s traffic was “terrifying” to the company. [Continue reading…]
