It’s a bit like saying a drug dealer has no accountability because it’s the user who buys the drugs. In this case FB is well aware of the consequences of their actions, and even worse, their total inability to do anything when it’s not in a dominant language. This has had profound consequences in places like Myanmar and India where disinformation spreads like wildfire and leads to the killing of people. You’d think they’d step back and go “whoa, this isn’t what we intended for FB to be” and do something about it. The opposite has happened.
What came first though, the chicken or the egg?
What came first, the content in an unbiased fashion and then the algorithms were trained on which content generated best engagement and it got promoted
or
did Facebook just behind the scenes start pushing bad content on a whim with no backing information? I don't think that happened
