Privacy ist mir Wurst. I Got Nothing to Hide.
2025-06-13 , Main Stage - Cinema 10

This is a talk about "having nothing to hide." A talk about oversharing in the age of TikTok and Instagram, about doxing in the era of public blockchains, and about data sovereignty in a world dominated by centralized repositories. Why is privacy so often dismissed, and what does it really mean to give it up?


Privacy, or the lack thereof, has become one of the defining issues of the digital age. Why has a fundamental right been so easily abandoned by the majority of internet users? What does it mean when people say, "I have nothing to hide"? This talk will examine the incentives and trade-offs on both sides: the companies building data-driven systems and the users who willingly, or unknowingly, sacrifice their privacy for convenience.

But privacy advocates aren’t off the hook either. We’ll explore how extreme approaches to privacy can sometimes do more harm than good, alienating the very people they aim to protect. Instead of fear-mongering, can we find a more effective path forward? Perhaps the carrot is mightier than the stick. What would a privacy-first future look like if it was driven by benefits, not just threats?
