Isn't it a chicken and egg problem? The existence of this illegal market can never allow legitimate sales to exist sustainably.

When people can just google " f movies <insert_movie_name_here>" and watch the movie series you mention in HD, unfettered, and ad networks reap the reward of turning a blind eye. . . this makes a sustainable market for legitimate goods impossible because the scale simply does not exist for enough people to subscribe to a streaming service or to invest in paying to watch so the costs drop at scale etc.
