Privacy Sandbox, Google's answer to third-party cookies, promised within months.One version that's been reported is titled "Turn on an ad privacy feature" and there's a button that says, "Turn it on." Google's popup appears to have regional variations that make the call to action and the button labels clearer and more consistent. But some developers claim Topics may be useful for browser fingerprinting and both Apple and Mozilla have said they won't adopt Topics due to privacy concerns. Google has offered repeated reassurances that its Topics API does not allow companies to identify those whose interests inform its ad API. "I don’t want my browser keeping track of my browsing history to help serve me ads, and I definitely don’t want my browser sharing any function of my browsing history with every random website I visit," he said via Twitter.Īnd VC Paul Graham has derided ad targeting tech as spyware. I definitely don’t want my browser sharing any function of my browsing history with every random website I visit Matthew Green, a cryptography professor at Johns Hopkins University in the US, just encountered the popup and expressed his dismay. Nonetheless, there's more push back now against the norms preferred by Google and other ad industry firms. Where third-party cookies were previously used to deliver targeted ads, Chrome users also had to take steps to disable them. It otherwise doesn't change the status quo. It's worth noting that this popup does explicitly say, "you can make changes in Chrome settings," and that you can switch off the Topics API support using those linked controls. Will Dormann, a security researcher with the Carnegie Mellon Software Engineering Institute's CERT Coordination Center, noted last week that Google's popup provides a default "Got It" button that dismisses the popup pane and does "the exact opposite of what the title text describes" – it leaves Chrome's ad targeting based on browsing history active.
