A few bad apples spoils the bunch. You can have thousands of apples in a barrel, but a couple of bad ones can quickly make the whole barrel worthless.
For example, the New York Times makes the right call on integrity vs profits, access, etc dozens of times a day for years. Then one time 20 years ago they make the wrong call vis a vis Iraq weapons of mass destruction, and they've almost completely destroyed their integrity. Seems unfair, but as a consumer we can no longer trust them, and probably never should have.
