Agreed, what is good or bad depends on objectivity, not subjectivity. It depends on who makes the rules, on who the judges are. If we are our own judges of each other's content, comments, etc, then we all determine, define, what is good content and what is bad content like you said, in the eye of the beholder, with all doing what is right in his or her own eyes as mentioned in the Bible before the time of the Judges.
