If we are living in a world where the ‘free’ stuff is paid for by advertising, then it’s best to be explicit about it…:
[…] While there has been consumer pushback when it comes to browser data privacy, Google explains that the content consumed by users of Chrome and other browsers is free only because it’s supported by data-driven advertisers. With this in mind, Google’s Privacy Sandbox initiative bridge the gap between consumers exploring online content for free while keeping private data secure. The move would also allow advertisers to gather a non-invasive amount of data on consumers without turning to shady practices such as browser fingerprinting.
A large part of the initiative revolves around users having more control over what they’re able to see and control in terms of data being collected. That’s where the experimental extension comes in.
