> Your URL bar is an ad. Your phone default settings and push notifications are ads. Your app store is an ad. Every new feature or OS update is an ad. Your new tab screen is an ad. Your browser updates are ads.

How do you define ads? Those are not ads in my book. An update is not an ad, I can't think of any valid interpretation of that other than "existence is an ad because people who interact with it might want to do do again" but at that point the word "ad" has lost all useful meaning.

To be fair, I think echelon was calling out that there are absolutely ads in browser updates now. "Try Firefox VPN!" "Look what's new in Chrome!", etc.
