How can someone ask @Haejin to compromise at all, much less from a position of (relative) weakness? If he is earning on his posts, regardless of anyone's opinion of them, isn't that his prerogative?

If people are really against his ideas, instead of criticizing him, persuade those that are upvoting him to not. That will be far more of an incentive for him to change than asking to compromise, for which he gains little to nothing.

Think of it another way: what if he were to say this same thing to you? How would you react? Or even better: what if one of us minnows were to post something like this about your posts?
