Unfortunately, many of the “journalistic” institutions are owned by large corporations who aren’t going to “speak truth to power” in fear of retribution.
We just saw this with ABC News’s settlement with Trump because its owner Disney wanted to stay in his good graces.
Let's be honest: the major journalistic outlets only "speak truth to power" when it means they get to criticize their outgroup. Which means any time Republicans have power, they're falling over themselves to speak up. But when Democrats have power, they are conspicuously silent. Time and time again this happens, and they have completely undermined their own credibility by doing so.
