How can Facebook promote meaningful interaction between users? By letting them downvote inappropriate comments to hide them. Facebook is now testing a downvote button on a limited set of public Page post comment reels, the company confirms to TechCrunch. But what Facebook does with signals about problematic comments could raise new questions about censorship, and its role as a news editor and media company.
Perhaps this is a chance to downvote negative comments on your ads and "clean" them up?

I suppose the potential cluttering of FB makes it worthwhile to keep the "downvoting" feature intact, even despite negative implications. Basically Zuckerberg thinks it will allow customers themselves to be moderators in a way, even though it may not always seem fair.
I dont see this as a threat whatsoever. It all boils down to statistics : if the "likes", and "thumbs-up" are more than "Downvote", it might have little effect.
Unless there is a benchmark number set, and a robot / aggregator put in place to compare total "Downvote" had , with a benchmark set, then it can be a threat.
