A comparable behaviour can be seen for years now on iOS. Chrome for iOS is advertised where possible, even if you would like to open a hyperlink from the show notes of a YouTube movie: You are offered to open this link with Chrome ("download"), Google App ("download"), or even with Safari ("open"). There's no real use for the user having Chrome on iOS as long as it has to use WebKit as a rendering engine, the same engine Safari uses. But there is surely a usage for Google, monetizing the user's browsing profiles.
