   CNN (NASDAQ:WBD) is canceling its 30-year-old media criticism show Reliable Sources, and host Brian Stelter is leaving the network.    The move marks the latest change from CNN chief Chris Licht, who made an early splash just after the formation of Warner Bros. Discovery by axing subscription streaming service CNN+.    Licht has been making cuts at CNN starting even before his official debut on the job May 1 of this year. And his actions are drawing additional scrutiny since newly prominent WBD investor John Malone has been critical of CNN for politicized coverage.
