Devil’s advocate: Microsoft, an ethically unclean company, is justified in using this tactic to compete with Google, because (a) Google did it to acquire Chrome users in the first place, and (b) breaking the browser hegemony at a user mindshare level (not rendering engine level) is worth some UX pain.
Note on (a): some will argue a difference between Google advertising Chrome on Google’s property (something they could do when bootstrapping Chrome) and advertising Chrome on other people’s property (something they could not do). But here, Windows and Edge are Microsoft’s property, like it or not.
