I think governments are slowly addressing "platforms". Not just computing platforms, but platforms in general. E.g. shopping platforms, gig-platforms. Platforms are like an economy inside an economy, with the platform-company being the regulator, and this can be a bad thing (much worse than if the government was the regulator).
Exactly, the best example with regards to the App Store is Apples own participation in large swaths of it with both iCloud storage (Dropbox, Google Drive, Box, etc), Apple TV+ (Netflix, Disney+, Amazon Prime Video, etc), or Apple Music (Spotify, Tidal, whatever Google has called their service for 2022, etc).
In each of these categories Apple are competing unfairly by demanding their competitors pay them 30% for the privilege of reaching over half the population of every first world country.
