"This is a one-time notification giving people the choice to set Bing as their default search engine on Chrome,” says Caitlin Roulston, director of communications, in a statement to The Verge. Roulston framed the pop-up as offering perks to Windows users, since they can get more chat turns in Copilot if they accept the notification. “We value providing our customers with choice, so there is an option to dismiss the notification."
