To some degree. But addiction describes a range of behavioral symptoms with a variety of durations and dynamics. The expected return of designing platforms to entertain 17-year-olds will decrease a little, but the expected return of designing a platform to entertain 13-year-olds will decrease a lot. By the time the latter group is monetizeable, they might move to a competitor's platform — just as prescription painkiller addicts have an easy time substituting heroin when they find it's cheaper. One thing that's particularly convenient for regulators in this case is the tendency of adolescents to deliberately change their behavior as they approach adulthood in order to reinforce a sense of personal growth. 18-year-old me didn't want much to do with games and movies for 13-year-olds.
