From 1 January 2025 a controller must let consumers opt out of targeted advertising and sale through an opt-out preference signal sent with the consumer's consent by a platform, technology or mechanism that does not unfairly disadvantage another controller, uses no default setting but requires an affirmative, freely given and unambiguous choice, is consumer-friendly, is consistent with federal and state law, and lets the controller determine whether the consumer is a Montana resident and has made a legitimate opt-out request.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
