Google has decided to show these popups by default to everyone that is browsing the web with tracking protection enabled since October 2022. This prompt has started to pop in our faces on most sites that integrate Google Sign-In as soon as we visit a page, often covering the content we are trying to view, and the website operators need to take specific steps to change the default behavior. We can only applaud DuckDuckGo for attempting to mitigate the destructive actions of Google.
