Final answer:
One privacy consequence of having an opt-out rather than opt-in policy is the potential for individuals to unknowingly have their data collected or shared without their explicit consent.
Step-by-step explanation:
One privacy consequence of having an opt-out rather than opt-in policy is that individuals may unknowingly have their data collected or shared without their explicit consent.
For example, if a website has an opt-out policy for sharing data with third parties, individuals who are not aware of this may assume that their data is not being shared. However, their data may still be collected and shared unless they actively opt-out.
This can result in a loss of control over personal data and potential privacy risks, as individuals may not have the opportunity to make informed choices about the use and dissemination of their information.
