It only allows them to TRY to provide ads to me, according to particular web requests, etc. It does not mean I am compelled to allow it to be displayed on the screen I own, regardless of whether I consuming from the free content stream they decided to emit.

I could cut out a small rectangle of construction paper and create a robot with a computer vision apparatus, and have it follow me around, constantly check if an ad is visible on the screen, and dynamically block my field of vision to ensure I don’t see it.

Or I could miniaturize that whole thing and place it as a browser plugin or mobile app.
