Facebook announced on Friday that it has removed two networks "for engaging in foreign and government interference."

Why it matters: Social media companies are under pressure to keep up with the deluge of state-linked online messaging aimed at altering popular opinion and voter behavior.

  • Facebook's head of security policy Nathaniel Gleicher wrote that the company removed two networks that engaged in coordinated activity "on behalf of a government or foreign actor."

Details: The social media giant said that each network had different origins and targeted different groups.

  • One network was active in the country of Georgia, which shares its northern border with Russia. It targeted domestic Georgian audiences.
  • A second network originated in Vietnam and the United States, and targeted those countries, as well as Chinese- and Spanish-speaking audiences around the world.
  • The accounts and pages included "impersonations" of media outlets, political parties and groups, as well as public figures.

Background: Facebook has come under fire for its failure to prevent the spread of targeted disinformation during the 2016 U.S. election, as well as similar state-coordinated disinformation campaigns in other countries.

  • There is growing concern that the Chinese government is using U.S.-based social media platforms to shape opinion abroad, particularly among the Chinese diaspora.
  • In September, Twitter announced that it removed thousands of accounts that had participated in a coordinated campaign, originating in China, to attack Hong Kong protesters and spread Chinese government propaganda related to the protests.

What they're saying:

  • "We’re taking down these Pages, Groups and accounts based on their behavior, not the content they posted," wrote Gleicher.
  • "In each of these cases, the people behind this activity coordinated with one another and used fake accounts to misrepresent themselves, and that was the basis for our action."

A virtual school year will likely push retailers even closer to the brink.

Why it matters: Back-to-school season is the second-biggest revenue generating period for the retail sector, after the holidays. But retailers say typical shopping sprees will be smaller with students learning at home — another setback for their industry, which has seen a slew of store closures and bankruptcy filings since the pandemic hit.

The economy has been tanking. Coronavirus infections and deaths have been rising. And the health care industry is as rich as ever.

The big picture: Second-quarter results are still pouring in, but so far, a vast majority of health care companies are reporting profits that many people assumed would not have been possible as the pandemic raged on.

How climate and business woes are sinking a natural-gas project

The Trump administration recently touted its approval of America’s first terminal on the West Coast to export liquefied natural gas. There’s just one problem: it probably won’t be built.

Why it matters: The project in southern Oregon faces political and business hurdles serious enough that those who are following it say it will be shelved. Its problems embody the struggles facing a once-promising sector that's now struggling under the weight of the pandemic and more.
