I am confused why Facebook needs news curators to begin with? Why can't the news just be organic entirely and use ML to curate it per person. I can understand blacklisting certain sites or topics just for pure sanity or appropriateness. Having people as curators just seems like wasted capital. Anyhow, I find this abhorrent, but I think Facebook has every right to do it as a private entity. I don't think they have a social responsibility to be 100% even. What does bother me is that they claim to be evenhanded, I do want transparency, especially when you are basically the monopoly in social media (excluding Snapchat and Twitter, they own everything.) This also presents a problem, I think with Twitter's new algorithmic timeline and why the real-time feed is vastly superior for their model (I'll beat this dead horse until Jack realizes how dumb it is.)
