The ability for someone with a news article or a game to only have you experience it if you pay their fee or watch their ads, preventing you from copying the content off your device or modifying it in some way that is unauthorized (removing ads or otherwise modifying the behavior to circumvent protection mechanisms) is pretty obviously the exact same idea -- not some mere metaphor -- and is a protection of the exact same "right" conferred by the exact same laws as allowing someone with a movie to only have you see it if you pay their fee or watch their ads... I am honestly having a difficult time understanding your confusion here :/.
