Our conversation with MacPaw’s Senior Software Engineer Serhii Popov and Product Manager Pavlo Haidamak continues to explore the intersection of product development, ethical data practices, and user trust. The team shares their experience building CleanMyMac and Setapp, emphasizing the importance of transparency, responsible data handling, and thoughtful feature design—like their decision to bring back the Space Lens module after unexpected user outcry. With real-world examples, they unpack how customer feedback and cultural perspectives inform their work, and why they believe developers should treat users as collaborators—not data sources.
