I got the impression that the Minds are proud of how many humans choose to live in their GSV or Orbital, when they are free to live anywhere and they appear to care deeply about humans in general and often individuals too.
Also, the Minds are not perfect Gods. They have god-like faculties, but they are deliberately created as flawed imperfect beings.
One novel (Consider Phlebas?) explained that The Culture can create perfect Minds, but they tend to be born and then instantly sublime away to more interesting dimensions.
