Béjar’s daughter was 14 when she told him Instagram was failing to keep her safe. So when he became part of Meta’s ‘wellbeing team’, he knew he had to speak out – and his testimony cost it billions

The Social Reckoning hits cinemas this Friday, but the real world has already been working on a sequel – or rather, a threequel. Directed by Aaron Sorkin, the movie is a follow-up to The Social Network, detailing the further misadventures of Mark Zuckerberg and his social media empire, and in particular Frances Haugen, the employee who in 2021 leaked internal documents that appeared to show Facebook was aware of the harms its products had inflicted.

It’s no spoiler to reveal the film climaxes with Haugen’s testimony to the US Senate, on 5 October 2021. That very same day, Arturo Béjar, a consultant on the wellbeing team of Instagram (which is also owned by Facebook), hit send on a long-gestating email to Zuckerberg and other senior Facebook executives on a similar theme. “I wanted to bring to your attention what I believe is a critical gap in how we as a company approach harm, and how the people we serve experience it,” Béjar began, before laying out some shocking statistics from his team’s survey. For example: 24.4% of 13-15-year-olds on Instagram said they had received unwanted advances, and 21.8% said they had been the target of bullying on the platform in the past seven days. Furthermore, 51% of Instagram users said they had had a bad or harmful experience in the past seven days. Only 1% of them reported it, and of those, 2% had the content taken down – so just 0.02%. This was a far greater degree of harm than the company’s existing measurements suggested. Zuckerberg never replied.

I paid for half of the tent, so I deserve equal use of it, even if we no longer live in the same country

Ava hasn’t used the tent in years, and I’ve stored it and paid for its upkeep. Surely I get first dibs?

After his mother died, Otto became convinced he’d been wronged by the forensic investigators – and that one of them was a fraud. The truth was even stranger

On a balmy, quiet evening in June 2020, Otto’s elderly mother, Doria, was fading in her Munich apartment. As she lay with her eyes closed, her pale face, framed by her white hair, was calm.

Otto, masked, gloved and draped in a sterile apron, dozed in a chair beside her. Otto, who sometimes goes by the name Rainer, and whose last name is only known as “Z” because of Germany’s strict privacy laws, was a doctor who had cared for his mother for years, ever since she had suffered a stroke and moved in with him. He described the course of that night to me. He woke to the sound of her short breath and tried to sit her upright. Her eyes were shut, and her lips pursed. She stopped breathing. Otto reached for his phone to call for help, but then Doria opened her eyes and stared into his. She smiled, drew one last deep breath, shut her eyes again, and lay still.

Some of the biggest names in European football will bid for a franchise in ESL-style league, now due to launch in 2028

The launch of NBA Europe will be delayed 12 months until 2028, with a pre-qualifying competition planned for next year to find four temporary members to join the 16-team league’s inaugural season alongside 12 permanent franchises.

The NBA is planning to invest about $10bn (£7.6bn) over 10 years in what sources have described as the sporting world’s biggest-ever startup competition. It is understood to have received multiple offers for the 12 franchises that exceed their targets, with prices expected to range from $500m to more than $1bn for the London franchise.

The UK state is dumping its responsibilities on our doorsteps, while green-lighting policies that lead us closer to crisis

Would you mind fixing the NHS? And while you’re at it, could you please build an anti-missile system in your garden? Then regulate the banks, replace the water mains, tax the very rich and use the proceeds to rebuild our schools. Well, come on people: what are you waiting for?

I exaggerate, but this isn’t very far from the approach taken by the government’s Prepare campaign. Crucial functions, way beyond the scope of individual action, are dumped on our doorsteps while those in power fail to act. As a result, our national resilience is arguably lower than at any time since the second world war. At the Labour conference last week, Andy Burnham promised “a Britain where people feel the country has got their back again”. To make good on that pledge, he will have to change almost everything.
