Volunteers and new recruits come together for ‘wikithon’ to put more detail about industry into public domain

“Anyone can edit Wikipedia,” the adage goes. But, it turns out, a relatively small number actually do.

What is worthy of a digital page in the world’s largest and most-read encyclopedia is decided by roughly 270,000 active volunteers, enthusiasts who populate the online resource with information on anything from 19th-century medicine to TikTok trends. Inevitably, some subjects are sidelined – the global south, notable women – but a new batch of Wikipedian recruits are waging war on one neglected topic: the arms industry.

Last week, in a classroom in central London, two dozen volunteers huddled around laptops and free servings of vegan Ethiopian food for what is known as a “wikithon”, an event of collective and in-person Wikipedia editing. Some were veteran editors in their 70s, others young students who had never registered an account before. But their targets include subjects such as Palantir, Project Maven and Nitro-Chem.

Tech platforms pillage public-interest journalism for profit. But we have leverage as they sow the seeds of their own downfall

Big tech companies pose an immeasurable threat: socially, politically, militarily and ecologically. They are also causing a profound crisis of information. The tools they design now serve as weapons of mass destruction against democracy. There is so much at stake that an urgent and broad mobilisation is required.

From the harvesting of personal data and the weaponisation of public opinion, to the destruction of jobs, the infringement of civil liberties and environmental damage, ordinary citizens are the main victims of this predatory economy – an economy with an agenda that aligns with the interests of the planet’s most authoritarian and reactionary states.

Jean-Noël Barrot criticises X owner in speech attacking foreign efforts to destabilise France before 2027 election

France’s foreign minister has accused Elon Musk of using his social media platform to orchestrate “massive online harassment campaigns” against European leaders as he took aim at foreign efforts to destabilise the country before next year’s presidential election.

Speaking at an Organisation for Economic Cooperation and Development conference on Tuesday, Jean-Noël Barrot pointed to the role that social media had come to play in the global battle over democracy. “The forces seeking to undermine democracy now dominate the information landscape, where they employ tactics designed to polarise public debate,” he said.
