The talk provides a compelling and well-informed perspective on the intersection of digital platforms, disinformation, and research. Chavalarias draws on his extensive experience as a researcher to illustrate the value of platform data for understanding social dynamics, particularly in mapping political polarization and detecting coordinated influence campaigns. His examples, such as the evolution of the French political space from 2016 to 2022, are concrete and demonstrate the analytical power of such data. However, the argumentation is somewhat one-sided, focusing primarily on the negative aspects of platform closures and political interference, without thoroughly discussing potential counterarguments or the complexities of platform governance. The scientific rigor is generally high, as he grounds his claims in his own research and references specific events and documents, such as the US National Security Strategy. The sources cited are limited to institutional links, but the talk itself is a primary source of expert opinion. The title accurately reflects the content, which is a critical examination of the challenges facing researchers in the age of private digital platforms. Overall, the talk is valuable for its insights into the current state of digital research and the urgent need for regulatory action, though it could benefit from a more balanced discussion of potential solutions.

The title accurately reflects the content, which focuses on private digital platforms, disinformation, and research blind spots.
