  The California Consumer Privacy Act (CCPA) secures the right to Opt-Out for
consumers in California. However, websites may implement complex consent
mechanisms that potentially do not capture the user's true choices. We
investigated the user choices in Cookie Consent Banner of US residents, the
plurality of whom were from California, through an online experiment of 257
participants and compared the results with how they perceived to these Cookie
Consent Banner. Our results show a contradiction between how often participants
self-report their Opt-Out rates and their actual Opt-Out rate when interacting
with a complex, CCPA-compliant website. This discrepancy expands the context
with which modern websites may implement the CCPA without providing users
sufficient information or instruction on how to successfully Opt-Out. We
further elaborate on how US residents respond to and perceive the GDPR-like
Opt-In model. Our results indicate that even though very few consumers actually
exercised their right to Opt-Out, the majority of US consumers desire more
transparent privacy policies that the current implementation of CCPA on
websites lacks.
