Martin Husovec is an associate law professor at the London School of Economics and Political Science (LSE). He works on questions at the intersection of technology and digital liberties, particularly platform regulation, intellectual property and freedom of expression. He's the author of Principles of the Digital Services Act, just out from Oxford University Press. Justin Hendrix spoke to him about the rollout of the DSA, what to make of progress on trusted flaggers and out-of-court dispute resolution bodies, how transparency and reporting on things like 'systemic risk' is playing out, and whether the DSA is up to the ambitious goals policymakers set for it.
