Another dark pattern (used to gain more positive ratings in apps) is:

    Do you love our app?

      Yes         No
       |          |
       |          |
     ______     ______
     Opens      Does
     AppStore   Nothing

It's a bit like saying, "Do you love candidate X?", and then giving instructions for voting only to those who answer "yes".

At the same time, if someone has indicated that they want to give my app a bad review, am I obligated to take them to the review point so they can do it?

I don't think that any of these dark patterns represent the breaking of obligations by any party.

Dark patterns don't represent anything truly sinister, and in most cases they are perfectly legal. They are just bad UX because they're dishonest about their intent.
