Because Facebook does internal studies to figure out that this is harmful for society, and it continues to do these things regardless. It's a form of tragedy of the commons. Mind you this is not a question of "just doing fiduciary duty". It could very well be argued that not fomenting fear and extremism in its userbase is good for business and the brand. Yet it chooses to be evil. And it's obvious why. Facebook is dying. There are almost no "regular" posts and people on there anymore. They're desperate to maintain some sort of engagement even if it means making the platform a gathering spot for the KKK.
