The fact that people use these poorly vetted sites as their primary source of news is unsettling. There is a lot of quality content, but it’s surrounded by a lot of garbage (from both the left and the right).
The NYT and WSJ both operate by much higher standards than I’ve ever seen on FB or Twitter. The newspapers are far from perfect, but they do abide by ethical standards. And most importantly, they are liable for their content.
You are chasing after a distinction without a difference.
Newspapers and TV media also have always received a lot of government pressure trying to spin their coverage or convince them to downplay (or emphasize) certain stories. I'm still confused about why it's suddenly so much more scandalous that anything similar happened with Twitter.
It's obviously bad in both cases, and it's clear that this kind of behavior has actually increased the attraction of misinformation and decreased trust in mainstream media -- which is the opposite of the intended result.
By the way, all the newspapers and mainstream media that were displaced by social media are almost all ad-based, for-profit enterprises too.
