All fallen empires will demand humiliation if you make them mad. (Except maybe the machine one? Not sure about them. Never tried annoying them. Honestly I try not to annoy any FE until mid game when I conquer them with a surgical strike.) The list of concessions just states everything that they want from you. It also applies the humiliation modifier for 10 years, one of the side effects of which is losing rivalries. If you aren't rivals, you won't lose any, but aside from the debuffs you get from humilition the other things on the list only apply if it's something you've done. For example, I recently made the control splinter mad because I did not want to make my borders pretty by abandoning the system they wanted me to, and it specifically stated humiliation would mean I lose all claims and rivalries on them. I was less than a century in. I had no claims or rivalries on them.
