What this episode covers

Scott Spencer, co-founder of Rewarded Interest and former DoubleClick and Google product leader, explains why cookie banners failed, how consumer privacy still feels broken, and what it takes to give users real control without hurting publishers or advertisers. Takeaways RTB wasn’t invented in a single moment. It emerged organically as multiple teams solved latency, bidding, and scale problems in parallel. Cookie banners fail both consumers and regulators by creating friction without real control or understanding. Rewarded Interest aims to replace site-by-site consent with centralized, programmatic privacy preferences across devices. Privacy control likely belongs above the browser level, especially as agentic browsing and AI assistants become mainstream. Changes proposed to GDPR may reduce protections around pseudonymous identifiers, increasing the need for user-centric control tools. The industry risks pushing users toward ad blocking if it can’t offer meaningful, trusted privacy solutions. Scott’s biggest regret from the RTB era isn’t technical. It’s not taking time to appreciate the magnitude of the transformation and the people behind it.

Wounded Warriors of the Cross Gary Pastoral and clergy mental health is a mostly ignored area, especially by those who live their lives as pastors in the clergy. The stigma of mental health within those who serve in the shadow of the cross is something that invokes the stigma of fear. Many of those in the clergy will choose to suffer in their despair rather than reaching out for help. Sometimes those suffering choose to wait until it's too late to get the real help that they need. At Wounded Warriors of the Cross our mission is to lift the stigma and the veil of silence that encompasses clergy mental health and assist those who suffer in silence. Wounded Warriors of the Cross is here to shed the light of Christ's love into those dark places.
