Apple still pushes ads to you. I can't recall how many times I saw ads in the App Store, and how many times they tried to push me into subscribing to whatever nonsense their executives' KPIs demanded (Apple Arcade+? News+? Music+?). No matter how many times I told Apple "No," they just kept pushing it. And now ads are coming to Apple Maps as well.
GrapheneOS has zero ads in the OS and main services.
