It’s not a privilege, it’s a researchers right! #DSA40

@lkseiling.bsky.social and I summarize what the European Commission decision in their case against X (I feel we should follow John Oliver and from now on call it Twitter again) means for researchers right to platform data access [in German]

Does anyone know the reasons behind this decision? In any case, this is not good news for independent scientific publishing. See firstmonday.org/ojs/index.ph... 2/2 #OpenScience

After around 30 years, #FirstMonday has announced that it will cease publication in May. Since 1996, the journal has been one of the first peer-reviewed journals to be published solely on the internet and made openly accessible. 1/2

Tor is widely used to circumvent government internet censorship. Due to the current total internet shutdown, Tor is no longer accessible from within the country. However, once connectivity is restored, Tor could again play a crucial role in enabling the flow of information.2/3

Since January 8, connections via Tor bridges from Iran have dropped from an average of around 10k per day to zero. Bridges enable indirect access to the Tor network, which is necessary because direct connections are typically blocked by the regime. 1/3

📢 Big news for platform researchers across Europe and beyond:

Today, the @ec.europa.eu adopted the Delegated Act for Article 40 of the Digital Services Act (DSA) – a long-anticipated milestone enabling researchers to request access to non-public platform data under Article 40.4.

Absolutely excited to host a roundtable on "Marginalised Voices and Perspectives in Computational Text Analysis" featuring @krangelie.bsky.social and @indiiigo.bsky.social at #COMPTEXT2025 🙌

We'll explore how bias and marginalisation shape methods and models - and thus scientific quality!
