DealBook Briefing: Behind Silicon Valley’s Big Cyberwarfare Pledge

Good Tuesday morning. Goldman Sachs is reporting earnings today. How will its trading unit fare? And for U.S. readers: Yes, today is tax day. Some links require subscriptions.

A ‘Geneva Convention’ for cyberwar?

In pledging not to help any government — including the U.S. — with cyberattacks against “innocent civilians and enterprises,” Microsoft, Facebook and 29 other tech companies are trying to distance themselves from the messy business of national cyberwarfare.

That may reassure some tech workers. (Earlier this month, Google employees protested their company’s work on a Pentagon project, saying the tech giant “should not be in the business of war.”)

The NYT’s David Sanger says the impetus came largely from Microsoft’s president, Brad Smith, “who has been arguing for several years that the world needs a ‘digital Geneva Convention’ that sets norms of behavior for cyberspace just as the Geneva Conventions set rules for the conduct of war in the physical world.”

Also striking: Who hasn’t yet signed, including Google, Apple and Amazon.

The context: The U.S. and Britain just yesterday warned about sweeping Russian cyberattacks on governments, businesses and private individuals.

Elsewhere in tech: Tesla halted production of its Model 3 to work out kinks. Netflix reported its strongest subscriber growth since going public. Investors are considering dropping Facebook from their FAANG bets, while a federal judge gave a photo-scanning lawsuit against the company class-action status. Amazon Business is reportedly holding off on selling drugs to hospitals. Coinbase is buying the paid inbox service Earn.com. And TaskRabbit has gone offline to investigate a possible hack.

The U.S.-China fight has pushed deeper into tech

Trump administration officials said that moving to block China’s ZTE from using U.S. components wasn’t a trade-related decision. But it’s hard not to see as the latest salvo in Washington’s fight with Beijing, particularly over technology. (Another Chinese tech giant, Huawei, is scaling back its U.S. presence.)

China’s trade deficit with the U.S. is widening. But China offered an olive branch today by loosening regulations for foreign makers of electric vehicles.

On currency concerns: The Treasury Department chose not to label China as a currency manipulator. President Trump disagreed: “Russia and China are playing the Currency Devaluation game.” The truth is more complicated.

What was Michael Cohen doing for Sean Hannity?

Now that Mr. Hannity has been revealed as a legal client of Mr. Cohen’s, the media world has wondered what Fox News star wanted from the lawyer used by President Trump and the disgraced Republican donor Elliott Broidy.

Mr. Hannity has denied paying Mr. Cohen legal fees and asserted that none of their talks involved a matter involving him and a third-party — i.e., a settlement. (The talks, he said, were brief and about real estate.)

More eye-catching is the Fox News host’s contention that he might have slipped Mr. Cohen a few bucks for attorney-client privilege, which appears to be right out of “Breaking Bad.” (And legally erroneous.)

#MeToo takes center stage at the Pulitzers

The NYT and The New Yorker shared the most prestigious Pulitzer Prize, that for public service, for their work on covering the harassment scandals in business, politics and the arts.

Steve Ballmer’s ‘shareholder meeting’ for the U.S. is today

When the former Microsoft chief set up USAFacts, he described its main project to Andrew as a 10-K for the U.S. government. Today, Mr. Ballmer will present its findings at what USAFacts says is a sort of annual meeting for taxpayers.

Mr. Ballmer said of the latest report, “Public companies owe this level of transparency to shareholders; I think citizens, as America’s shareholders, deserve the same.”

Watch the livestreamed meeting today at 1 p.m. E.T.
