Yes, in theory it would work if they limited it to their reaction to something said and thus show their thoughts about a particular point/post/comment.  But when they then abuse that power and use it as a tool to suppress, then they have gone too far.  I hope some big boys start policing their own because otherwise the "joys of this platform" will be too much to handle! :)

I tried to manage the comments so I didn't give you a full upvote.  But I failed.  So if you comment again, then I will make up the difference! :D
