I wouldn’t be so sure of that. Their edge in search and email is eroding. The general public wouldn’t see much difference if their default search engine was DDG. Not saying it’s not a monopoly, but I see it more as brand power than impossible to match by competition. Same for email or maps, you can switch on a individual level for nearly the same experience.

I’m way more concerned by Facebook in terms of monopoly, because here I truly don’t have a choice between products, just to opt out with social consequences. That’s not the case with search or email.
