Twitter blocks 5G conspiracy tweets

“We have broadened our guidance on unverified claims that incite people to engage in harmful activity, could lead to the destruction or damage of critical 5G infrastructure, or could lead to widespread panic, social unrest, or large-scale disorder,” Twitter (NYSE:TWTR) writes in a blog post.

Examples include, “The National Guard just announced that no more shipments of food will be arriving for two months – run to the grocery store ASAP and buy everything” or “5G causes coronavirus – go destroy the cell towers in your neighborhood!”.

Using blockchain to tackle COVID-19

Blockchain technology projects are being developed by companies like IBM (NYSE:IBM) and Ernst & Young to help with different aspects of coronavirus pandemic.

Applications? They can be an efficient way of connecting healthcare providers in need of medical equipment or help validate a person’s immunity.

The projects could run into challenges, however, if the data that goes on the blockchain is inaccurate and difficult to verify.

No post office aid without Amazon price increase – Trump

During a press briefing in the Oval Office, President Donald Trump said he would block federal aid for the U.S. Postal Service unless it raises shipping rates for Amazon (NASDAQ:AMZN) and other online companies.

Key quote: “The Postal Service is a joke. Because they’re handing out packages for Amazon and other internet companies, and every time they bring a package, they lose money on it. The Post Office should raise the price of a package by approximately four times.”

The Postal Service says it might not make it past September without help, and Congress has authorized an up to $10B loan from the Treasury Department.

Treasury Secretary Steven Mnuchin says his team is meeting with post office officials but that “certain criteria for a postal reform program ” would be part of any loan.

Trump has been calling for the Postal Service to raise shipment prices since December 2017, often mentioning Amazon by name in his arguments.

Zoom turns negative as Facebook introduces group calling feature (updated)

Zoom Video (ZM -1.1%) shares have gone negative, and Facebook (FB +1.4%) hits a session high after it unveils a group video chat feature.

Messenger Rooms will support free video calling for up to 50 people.

Regular Messenger video calls are limited to eight people.

The new Messenger Rooms feature will ramp up as the 50-person limit won’t be immediately available, but the calls will have no time limit.

Zoom by contrast allows up to 100 people to video chat for free, but with a 40-minute time limit.

Meanwhile, Facebook will also double WhatsApp’s video call limit to eight people from four people. And it’s adding video calling to Facebook Dating, to enable virtual dates there.

Stephenson out as AT&T CEO July 1

Randall Stephenson is stepping down as AT&T (NYSE:T) CEO on July 1, CNBC says.

Chief Operating Officer John Stankey is taking over the top job, according to the report.

Stephenson retires after 13 years; he’ll remain as executive chairman of the board until January 2021. Later this year, the board will elect an independent director to chair the board after Stephenson’s exit.

Earlier this year – during a conflict with Elliott Management that encapsulated disputes over management – Stephenson had said that he had committed to stay with the company through 2020 but with no commitments beyond that.

Stankey will join the board as well.

Here’s David Faber at home. He notes Elliott partner Jesse Cohn saying they support Stankey as the next CEO and that Elliott has been engaged with the company throughout a search process.

Stankey has been COO since October and joined AT&T in 1985.

Updated 10:33: After a quick few hitches in the stock, shares are up 0.5%, not far off where they started the day.
