This raises one of the problems with company-sponsored media that has been a problem since Pulitzer and Hearst. Your bosses and sponsors will always have opinions about what news is fit to print.

So during the cold war never a bad thing was said about GE (we bring good things to life!) despite how they were pushing our elected officials to buy more nuclear warheads, even when we had plenty. GE bought a lot of commercial time from all three networks and no one wanted to disrupt that cash flow.

This might be a benefit from federated social media, that burying a story becomes impossible requiring only a bit of vigilance from its end users.
