You wrote that without laughing? Over the last 10-20 years they openly disgarded any ethical standards. They no longer investigate, they no longer report the truth, they no longer leave their personal bias, bigotry, and views at the door. I've seen repeated comments by well-known reporters saying their views must be shared, are more important than the truth.
The way to look at this is think of the mass media as the Mob.
They are lying immoral thieving enemies of the people.
But—they still have an internal code.
They broke that code.
Of course they act unethically on a daily basis, but that doesn’t mean we should not point out when they have broken their own ethical standards. This last move by CBS has shocked the few honest journalists left. Even the dishonest ones are self-serving and realize that this unprecedented move by CBS management will hurt them in the long run. Anonymous sources will dry up.
