Google Chrome downloads 4GB AI model to your device without permission (www.tomshardware.com)

Security researcher Alexander Hanff has revealed that Google Chrome is downloading a 4GB AI model called "weights.bin" to users' devices without their consent. This action is part of Chrome’s integration of on-device AI, which analyzes system hardware to determine eligibility for the download. Hanff compares this behavior to a previous finding with Anthropic's software, where modifications were made silently and without user prompts, highlighting a concerning trend among major tech firms that prioritize feature rollout over user control and transparency. The implications of this incident stretch beyond user experience, raising significant legal concerns under European privacy regulations, including potential violations of the GDPR and ePrivacy Directive. Hanff argues that such silent downloads could have far-reaching environmental impacts, using considerable energy and contributing to CO2 emissions. Moreover, for users with limited data plans, the unannounced download can result in unexpected financial costs. This pattern of behavior, where user devices are treated as passive deployment targets, underscores growing criticisms of large tech companies that often design features with little regard for user agency or consent.
