Google has been bombarding its users with ads for Goggle Chrome for years.
As soon as you do a search in Google and use Edge or Firefox, this banner is displayed.
Microsoft has now retaliated by displaying a banner injected by Edge that you should better use Edge after all.
It is shown when you hit the Google Chrome Download page.
I'm not a fan of Microsoft (nor Google), but I find this tactic ingenious.[1]
