The media (especially in today's environment) works to sell ad views, not make the reader more informed.
Way (way) too many people think that because the media confirms their beliefs, the media is honest.

And the wider the margins and volumes the more competitors have incentives in making gigantic investments.
Otherwise companies can absolutely get a monopoly and cement it. Buy up competition, pressure adversaries, hog resources and so on.
