It just turns into opinion about how the site should work, then. Maybe I would like to see that person's input and snark. It's not my content they're posting on, but it's still my user experience being (potentially) diminished by letting someone else decide. In most cases, if you have someone muted, I probably would too. I personally would liberally apply the mute button on anyone who thought behind-the-back snarking is appropriate.
And there will be a hierarchy of opinions about how it should work. Those that favor functionality for individuals will be overruled by those who favor functionality for the community. Period. This is why content providers have more power over what you see than content consumers. It has to be that way or else your content providers leave. For example, I know at least three people who are "taking a break" from Hubski because the sheer number of assholes with opinions is overwhelming right now.
