India Bets on AI Detection. Every Regulator Should Watch What Happens Next. India's rules are correctable, write Mahsa Alimardani, Jacobo Castellanos, and Bruna Martins dos Santos from WITNESS.

As we all recover from Delhi and endless news about it, last friday marked the end of the summit but also the day when India's IT Amendment Rules 2026 on synthetically generated information (SGI) or synthetic audio-visual content came into force.

Deepfake ‘Nudify’ Technology Is Getting Darker—and More Dangerous Sexual deepfakes continue to get more sophisticated, capable, easy to access, and perilous for millions of women who are abused with the technology.

@wired.com and @mattburgess1.bsky.social have been doing an incredible job reporting on the creation of NCII-oriented Deepfakes by users of both Twitter and Grok. It was a pleasure to speak with him on this new article regarding the broader landscape of nudify tech.

Happy to speak to @nrc.nl on the risks emerging AI systems and its intersection with adult content and creation of NCII content. As the risks are higher, we need more concrete safeguards from the companies themselves other than blank prohibitions of producing content in certain contexts.

I wrote about Iran's protests for @theatlantic.com: how AI manipulation and the suspicion of it is being weaponised to dismiss real footage of protests.

This piece draws on work from my stellar team at WITNESS and years of studying information controls in Iran and beyond.

On our latest for Tech Policy Press, shirin anlen and I highlight the urgency of addressing NCII and CSAM as we see new interactions between Generative AI and adult-related content. What happened with #Grok this week is not an isolated case, just the culmination of years of misogyny online.

Trump Ends America’s Leadership on Internet Freedom | TechPolicy.Press By walking away, the US is dismantling the mechanism that once turned Western values into a lifeline for those behind a firewall, writes Konstantinos Komaitis.

On Wednesday, President Donald Trump withdrew the United States from 66 international bodies, including the Freedom Online Coalition. With this move, the US has formally stepped away from a core part of its leadership of the global Internet norms it once helped build, writes Konstantinos Komaitis.

Dear @vonderleyen.ec.europa.eu, the digital omnibus is the opposite of what we need.

In the era of hybrid warfare, we must make it HARDER to WEAPONISE our digital infrastructure against us — not EASIER.

🚨 Brussels, today 🚨Ursula! Stand up for Europe – not for Trump’s tech bros!

As the EU unveils its “Digital Omnibus” today, we're rolling out billboards calling on @vonderleyen.ec.europa.eu to stop bending to US and Big Tech pressure and enforce our digital laws #StandUpUrsula

I really wish that the European Commission + member states integrated the narrative about fostering innovation with the good old speeches about protecting digital rights and sustainability. Because at the moment this conversation is looking like a blank check for the private sector.

The EU strategy for fostering sovereignty is about providing funds to foster innovation but ITS ALSO about making sure regulations are not overburdening for companies. And thereno acknowledgement that these efforts - incl. the omnibus - will benefit actors that have not complied with EU legislations

The good old fallacy that protecting rights can hinder innovation being deployed as the baseline for the deregulation efforts. The lack of rights protecting groups and civil society at the Summit are a good reinforcement of that (only Article 19 and Sovereign tech Agency are speaking).

Little to no interventions about market concentration of digital services, and a rather contradictory line from Commission Representatives about how the EU is fighting concentration while reminding the industry that the Omnibus efforts might not end tomorrow. Aka. we can expect more simplification

While following the sessions I noticed the following:

Way too many nods to how the US is fostering its innovation sector with very few guardrails to industry: a confirmation that the movement on sovereignty here in the EU is more about ensuring competitiveness than breaking up big tech monopoly;

Following the #EUSovereigntySummit and the feeling is of utter disappointment. To see the much needed sovereignty umbrella being used to legitimize the erosion of rights through the omnibus proposals is just not where i imagined a continent that was so blatant about digital regulations going.

WITNESS has a group of 127 civil society orgs, trade unions, and public interest groups urging the EU to halt changes to the AI Act and GDPR. Reopening landmark laws would weaken the very safeguards that keep surveillance and abuses in check. #digitalOmnibus

What a bizarre and strange world we live in. To see Brazil framed as a national security threat to the U.S. based solely on sovereign and legitimate decisions taken by the Supreme Court that helped save Brazilian Democracy is a real absurd. Colonialism 4.0.

E como a linha de questionamentos sobre a validade de regulações como o AI Act ou o DSA, e no brasil a recente decisão do STF, parece ser uma nova e sedimentada diretriz de politica externa de Trump.

Em ambas conversas destaquei a linha de completo desrespeito por decisoes soberanas legitimas adotadas por instituições brasileiras, e a forçada de barra do governo americano ao utilizar a aplicação de tarifas para tentar emplacar a agenda "desregulatoria" ao redor do mundo.
