mrkstu's comment was:

If you're relying on Apple (or Google) to feature you in their search results, you're already at their whim with no recourse.

But your response is:

No one is saying they are responsible for promoting your app.

Does higher search placement not equate to promotion, in this case?

Also, I looked it up: https://en.wikipedia.org/wiki/Just-world_hypothesis

I'm not sure how it relates to my questions.
