Google is certainly a monopoly in several sectors, search and YouTube come to mind. Amazon is a duopoly with Walmart and both need to be dismantled, but the damage to main street was done a long time ago. I'm not sure where Apple is a monopoly. People argue the App Store but only for the iPhone and iPad, but I feel that takes some mental gymnastics since it's somewhat niche and other stores for other phones exist.
