"The video is part of a paid Israeli government campaign of posts on Google-owned YouTube that 'focus on whether or not a famine is taking place in Gaza,' according to an internal Google email reviewed by The Washington Post." wapo.st/47dlXDu
As famine struck Gaza, Google let Israel run YouTube ads claiming, ‘There is food’
An internal Google email said it received many complaints about Israeli government YouTube ads about food access in Gaza, but ruled they could remain online.

Under Article 21 of the DSA, out-of-court bodies review moderation disputes. One such body, Appeals Centre Europe, has released its first transparency report.
@ramshajahangir.bsky.social spoke with Thomas Hughes and Paddy Leerssen about what these early findings suggest.

In today's Briefing: I found 114 ads for AI nudifiers on Meta.
The copy of the ads included the word "undress," which isn't a sophisticated term to watch out for.
As always, I flagged these ads to Meta, which took them down. Google also took down a related app.

Chuffed to see my new draft paper on platform ownership billed as "hidden gem of the week" over at the Syllabus 👇
Ownership of social media platforms by tech oligarchs like Musk and Zuckerberg has become a decisive force shaping content governance. Our hidden gem of the week shows how individually-owned firms enable direct ideological and political instrumentalism.

SPUI25: Hoe kunnen we het recht inzetten om mensen minder te laten vliegen?
Luchtvaart is een vervuilende bezigheid: Iemand die van Lissabon naar New York vliegt en terug, veroorzaakt ongeveer evenveel uitstoot als een gemiddelde EU-burger doet door zijn huis een heel jaar te verwarmen. Sinds 1992 maakt de EU wetten en beleid om de uitstoot van de luchtvaart aan te pakken, maar ondertussen heeft de uitstoot door de luchtvaart recordhoogtes bereikt. Hoe kunnen we dit inperken?

The Rising Power of Big Tech
In a moment of rapid change for global politics, Big Tech platforms and their owners are shaping up to be international power brokers. Trump’s White house cozies up to Silicon Valley oligarchs as Elon Musk and Mark Zuckerberg, and clashes with the EU over its platform laws. How does the power of Big Tech affect our democracies, and can it be contained? In this panel discussion, researchers Theresa Josephine Seipp and Paddy Leerssen will discuss their latest research on platform power and regulation.

The 'Instagore' story from last week is absolutely nuts and really flew under the radar.
No clear explanation either. Theories I've seen:
- deliberate sabotage, e.g. from a disgruntled employee?
- coding error, e.g. inverting ranking scores to show lowest first?

Online gambling is a social crisis in the making, and a ticking time bomb for online content regulation.
Growing up in Holland, bookies and sports betting were practically unheard of. Our neoliberal government deregulated online casino's in the early 2020s, and now it's everywhere. Disgusting.
