About this Talk

Admit it. You hate them. I hate them. It started with a simple feature request: "add a cookie banner." It ended in a legal black hole from which your product owner has yet to return.

For years, the European Union has tried to give users control over their data. A noble quest. In reality, it has unleashed a decade of chaos, creating a digital minefield that we, the people in IT and legal, are forced to navigate daily. The result? An internet flooded with UX monstrosities, dark patterns, and "Accept All" buttons that are often little more than compliance theater, not a genuine choice.

In this 22-minute, jargon-free session, we're diving straight into that chaos. This won't be another boring slide deck about legal articles. This is a field report from the trenches.
