Microsoft CEO Satya Nadella warned that enterprises are exposing proprietary knowledge when they use third-party AI systems, arguing that prompts, tool interactions, and corrective feedback can transfer valuable internal expertise to model providers. He described the dynamic as a "reverse information paradox," saying customers may pay twice for AI services—once in fees and again in knowledge that improves a vendor’s models—while urging organizations to set clear trust boundaries, keep control of evaluations and feedback, and avoid dependence on a single provider.
The concern intensified as Google updated Search privacy settings so media from search interactions—including images, files, audio, and video—can be used to develop and improve its AI models unless users opt out. Separate reporting said enterprises are increasingly weighing private or open models against closed AI services because of fears that sensitive business data could be retained, learned from, or used to strengthen vendors that may later compete with them, even as major providers maintain that some API traffic is excluded from training or covered by zero-retention options.

Microsoft CEO Satya Nadella said enterprises risk giving AI providers proprietary knowledge through prompts, tool usage, and corrective feedback, describing it as a 'reverse information paradox.' He called for stronger protections, trust boundaries, and retaining control over evaluations and feedback.
Google updated its Search privacy settings so that media saved from interactions with Google Search services, including images, files, audio, and video, may be used to develop and improve its AI models and related services. The change reportedly auto-enrolled users unless they manually opted out through privacy settings.
