Of course this is exactly how Facebook want it. To appear as the light touch impartial platform where "everyone is free" to communicate. Except in the background they play with who sees what to increase engagement and run experiments.
With the black-box of algorithms used to target content we can only guess what is really happening. But as every media company knows, controversy sells. So I'll need a lot of proof that generating controversy isn't exactly what Facebook is doing on their platform.
On hot-button topics, that's simply not true. Google maintains manual rankings for all sorts of things, and especially manually maintains search suggestions so as to not lead people down the "wrong" path.
I personally try to do my part by stomping on this dumb sentiment like a cockroach whenever it pops up.
And there is a fundamental difference between Google's algorithm and Facebook's: control. Google requires user input through search, Facebook decides what shows up when you open the app/site based on an algorithmic feed. In one case the user has some idea that what they're doing is interacting with an algorithm and they can change their search terms if they're not satisfied with the results, in the other the algorithm is in the background making decisions without making itself obvious.
There's no inherent contradiction when people say "this simple, transparent, obvious algorithm is better". Even if implementing it would in fact result in forgoing billions of dollars.
If my feed is going to have posts shared by others (even non-friends) or, worse, op-eds in it, then FB is vouching for whatever I see. If they share a link with 50 million people, they're certainly responsible for the consequences.
Worse is the ad side, where Facebook wants to continue to profit from well-funded wars against science while still claiming to be neutral.
If you get paid to broadcast a message and then broadcast it, you are not neutral.
