That's only because they don't have the market share. If Apple ever becomes dominant in this arena they would absolutely take the opportunity.

That's debatable. Unless you have the TV button open the home screen and not the Apple TV app, Apple TV+ content when not subscribed can be seen ads.

My Shield TV doesn't either.
