An email Amazon sent to many of its employees Friday morning telling them to remove TikTok from their mobile devices was sent in error, the company said later the same day.

Driving the news: The original email said TikTok, the popular social video app that's facing criticism for alleged ties to the Chinese government, was a security risk for Amazon workers who accessed company email on their phones.

Facebook is considering blocking candidates and causes from purchasing political ads in the U.S. ahead of the 2020 presidential election in November, Bloomberg reports.

Why it matters: The tech giant has been facing intense scrutiny for allowing politicians and advocacy groups to micro-target political ads on its platform, and for not fact-checking the ads. It has repeatedly defended its political ad policies, citing free speech. Banning ads leading up to the election would be a major reversal.

Amazon, citing security risks, told its employees Friday to uninstall social video app TikTok from any mobile devices they use to access their work email.

Why it matters: The move comes amid a broader backlash against TikTok, in part due to questions around possible ties to Beijing. TikTok is owned by Chinese tech firm ByteDance.

ByteDance is considering new corporate structures for its TikTok business, as it comes under political pressure in the U.S. and other countries for ties to China's government, per the Wall Street Journal.

Why it matters: The Beijing-based firm is the world's most valuable privately held tech company, estimated to be worth upwards of $110 billion by direct investors and $150 billion in recent secondary market trades.

After a couple weeks of developer-only testing, Apple has made available a public beta version of iOS 14, the software that will power iPhones starting this fall.

TikTok users have again tried to prank President Trump, flooding his official campaign app with thousands of one-star reviews, Bloomberg eports.

Why it matters: Generation Z is retaliating against the president after his administration has floated banning the Chinese-owned app — a favorite among their cohort — in recent days over data privacy concerns, which TikTok denies.

As tech's giants prepare to face off with antitrust enforcers this summer, they will draw support from an array of predominantly right-leaning defenders ranging from influential former government officials to well-connected think tanks.

The big picture: The Justice Department, the Federal Trade Commission and the states have multiple investigations of monopolistic behavior underway targeting Facebook and Google, with other giants like Amazon and Apple also facing rising scrutiny. Many observers expect a lawsuit against Google to land this summer.
