If the boxing game promised fair competition (censorship resistances) but the rules encourages other forms of behaviour (whales turning day into night) then surely those who invested their time and effort into the game, or in this case created content, have the right to speak out?

This is another submissive argument that's been posted: you didn't put any money in/you are getting more out of this than Facebook so don't complain. It's quite counterproductive because it suppresses constructive discussions.
