How do we make open source really fair for all? Open-source designers and developers take a lot of ethical ownership of their projects. Despite this, there is always the danger of accidentally creating deceptive designs that steer users into choices harmful to them - aka dark patterns. We could help them with open designs by creating fair patterns, but where do we even start?

In the last years, I have studied and talked with different populations that are affected by these designs, and professional UX/UI designers that face the challenges related to deceptive designs. A repository of "fair patterns" or "bright patterns" as opposed to manipulative design is a necessary tool to mitigate these harmful designs, but the burden of creating these is very high. Open source design presents as a key to creating these patterns. In this talk, I will address the main problems that UX/UI designers face in the context of manipulative designs and discuss some unexpected challenges and potential solutions. With this I help the open source design community in creating more ethical interfaces with free-fair patterns: free from these deceptive patterns, free to use, and fair for all.
