You're kidding, right? iMessage has massive scale. Several years ago, Apple revealed they were processing "several billion" iMessages per day, and it's hard to imagine that number hasn't simply grown since then. As for the iTunes Music Store, I could believe that it's not used as often as previously because of the popularity of streaming services, but Apple also runs one of those streaming services (Apple Music), and they run iCloud Library which gives you access to all of your purchased music on all of your devices, and of course they also run the iOS App Store and you can't argue that doesn't have massive scale.
