I'm throwing my bullshit flag for this post, specifically your title. When I read your title, I thought netflix was altering the content of user reviews, and removing bad ratings. I was pissed. Turns out, they are overhauling the entire review+rating system. That is technically consistent with what you said, but I can't help but think you worded it that way deliberately to mislead people. Also, the implication that the Amy Schumer stuff caused this is silly. They wouldn't overhaul their entire product that quickly, and "trolls" can just as easily mass downvote her videos. The decision doesn't make sense as a reaction to the Schumer flop.  Binary like/dislike ratings are in use by just about every content provider - examples, youtube, facebook, reddit, and ... voat. The article explains why. A simpler decision lowers the barrier to participation, so they get more data. More data lets you make better recommendations - it's basic machine learning.
