I agree, Newsfeed is divisive and toxic. I feel like Facebook was too slow in de-emphasizing it from the core product. But Facebook has become a lot more than that for so many people. I've seen a lot of people that have been able to make a better living thanks to Facebook's network effects.
This isn't thanks to the efforts of Facebook, but a byproduct of their huge social graph. I don't like Facebook as a company but I recognize the value in this, especially for people in less developed countries.
