Qualcomm-owned Arduino quietly pushed a sweeping rewrite of its Terms of Service and Privacy Policy, and the changes mark a clear break from the open-hardware ethos that built the platform. The new documents introduce an irrevocable, perpetual license over anything users upload, broad surveillance-style monitoring of AI features, a clause preventing users from identifying potential patent infringement, years-long retention of usernames even after account deletion, and the integration of all user data (including minors) into Qualcomm’s global data ecosystem. Military weird things and more. Several sections effectively reshape Arduino from an open community platform into a tightly controlled corporate service with deep data extraction built in. The most striking addition: users are now explicitly forbidden from reverse-engineering or even attempting to understand how the platform works unless Arduino gives permission. That’s a profound shift for a brand long embraced by educators, makers, researchers, and open-source advocates.
