CNN is an instrument of influence more than a business.
It dominates foreign views of the US for instance, as the standard international source for US news and opinion.
Ultimately it belongs to AT&T, and one must go there to ask why they maintain it, with such an editorial line. It serves someones interests of course, but what these are and who it serves is unclear. We can guess, but we can’t know for sure without someone senior breaking omerta.
Note that several large enterprises own such leftist media entities, or are closely associated with them. In part I think it is a form of protection-money paid to the bureaucratic system. Carlos Slim to the NYT for instance. He does not care about politics at all, other than to keep the rules working his way.
Time to break up AT&T.....again
