I have never understood why Microsoft didn't do this with Microsoft Edge. So many people use Google as their homepage, and Google has a "Please download Chrome" notification the homepage, always, whenever you aren't using Chrome. Considering Microsoft Edge is based on Chrome... what's to prevent Microsoft Edge from telling Google, "Hey there, I'm Chrome!" just to screw with the notification? Or heck, why not have a built-in lightweight Ad-Blocker that detects "We recommend Chrome" popups and hides them?
