Good morning. 🗣️ This could be U.S., but...: "Cafes bustled with customers, parks teemed with sunbathers, and the first Apple store to reopen outside China had lines snaking out the door as many South Koreans — almost all wearing masks — emerged from months of self-isolation," Bloomberg's Kanga Kong reports. "South Korea launched a massive testing and contact-tracing campaign that significantly curtailed the outbreak and kept many businesses and factories open. The number of new cases fell to 18 on Friday..."

• The home front, via NBC's Sarah Fitzpatrick et al: "Testing for the coronavirus would have to be at least doubled or tripled from its current levels to allow for even a partial reopening of America's economy, public health experts say, but it is unclear how soon such an ambitious goal could be reached amid persistent shortages of testing supplies and a lack of coordination from the Trump administration."

Fighting the virus

Mark Zuckerberg releases COVID-19 maps

Moving the Market: Mark Zuckerberg tells us that Facebook will today release the first county-by-county maps showing where users have voluntarily self-reported COVID-19 symptoms, an effort to help health officials better track the spread of the disease.

• "Overall, since experiencing symptoms is a precursor to going to the hospital or becoming more seriously ill, these maps could be an important tool for governments and public health officials to make decisions on how to allocate scare resources like ventilators and PPE, and eventually when it's safe to start re-opening society," Zuckerberg said.

How it works: The maps, which will be updated daily, use data from a voluntary Facebook survey operated by the Carnegie Mellon University Delphi Research Center. The data doesn't include individuals' specific movements, and the survey, which is used to generate the maps, is something people must opt in to.

• Researchers have already been using Facebook's maps showing population movement, which are created using the social media company's access to aggregate location data.

• "I think providing aggregate data to governments and health officials is one of the most important tools tech companies can provide," Zuckerberg said.

The big picture: Big tech is making serious efforts to use their vast networks and data-collection tools to help provide a clearer picture of the outbreak and possibly create systems that will help states ease lockdowns. Apple and Google have partnered to build a system for smartphone-based contract tracing.

• Instagram co-founders Kevin Systrom and Mike Krieger, who left Facebook in 2018, launched a website last week to track how COVID-19 is spreading in each state in real time.

What's next: Zuckerberg has an op-ed in today's Washington Post announcing the new maps, as well as Facebook's plan to take the effort global. "We're starting to run the surveys globally this week and should have the first reports of global disease prevalence soon," he told us.

Big questions

About contact tracing...

Big in the Bay: "If and when lockdown restrictions are lifted in the U.S., would you agree to let the government anonymously track your interactions with people within a 6-foot radius to control the spread of Covid-19?" Recode's Shirin Ghaffary asks.

• "That’s an increasingly urgent question as President Trump and state governors debate how and when to safely reopen the US economy — and as technology is being touted as a solution that would help people reenter public life."

The big picture: "If [tracking tools] work as intended, they could help end a once-in-a-lifetime public health crisis. But if ineffective, they could provide a false sense of confidence in our abilities to control the virus and allow it to spread further."

• "On top of all that, even if these tech solutions successfully slow Covid-19’s spread in the US, they pose serious, yet-to-be-determined risks to Americans’ privacy."

🇦🇺 Big Down Under 🇦🇺

Breaking overnight: The Australian government will require Facebook and Google to share advertising revenue with local media outlets. It is one of the first countries to require tech giants to pay for the news that appears on their platform.

Bad times in Burbank

Bob Iger stops paying 100,000

Bad times in Burbank: Disney chairman Bob Iger and chief executive Bob Chapek will stop paying more than 100,000 employees this week, or roughly half its workforce, because of coronavirus, the FT's Anna Nicolaou and Alex Barker write.

• The furloughs, which Disney announced earlier this month, will save the company up to $500 million a month, JPMorgan's Alexia Quadrani estimates. Disney has also cut executive pay, and Iger has decided to forego his entire salary.

• "But slashing fixed costs in a more severe way than other theme-park owners... poses significant risks to the reputation of the century-old empire," Nicolaou and Barker write.

The big picture: Disney, which has seen almost all of its businesses suffer on account of the pandemic, is taking perhaps the most aggressive cost cutting measures of any major media company. It's being watched closely by others as a potential harbinger.

Terms of Disengagement

Harry, Meghan vs. the tabloids

Moving Malibu: Prince Harry and Meghan Markle say they're declaring a new policy of "zero engagement" with the four major British tabloids, saying they will no longer "offer themselves up as currency for an economy of clickbait and distortion."

• In letters to The Sun, The Daily Express, The Daily Mail and The Daily Mirror, the Duke and Duchess of Sussex accuse the papers of knowingly publishing stories that are "distorted, false, or invasive beyond reason."

• "We are writing to set a new media relations policy," they write. "There will be no corroboration and zero engagement."

• "This policy is not about avoiding criticism. It’s not about shutting down public conversation or censoring accurate reporting. Media have every right to report on and indeed have an opinion on the Duke and Duchess of Sussex, good or bad. But it can’t be based on a lie."

What's next: "The new arrangements will mean the tabloids will be barred from receiving updates and photographs from the couple. But the newspapers may also be blocked from attending the couple’s media events," FT's Mark Di Stefano writes.

• The big picture: "It is the latest in a string of public statements made by the couple against the UK tabloids in recent years. Last year, Prince Harry compared the media coverage of Ms. Markle to how the tabloids covered his mother: 'I lost my mother and now I watch my wife falling victim to the same powerful forces.'"

🏀 What's next:"The Last Dance," the ESPN-Netflix docu-series about Michael Jordan's final season with the Chicago Bulls, premiered last night. It's fantastic.

See you tomorrow.
