ED is right. The droids were made with the Rakatan technology and were capable of self-repairs and self-maintenance. Obviously, HK mentions that he can take care of himself but lacks the ressources to do so which is why he ended up on Tatooine in the hands of a lousy mechanic.

Shussh! Don't give them any ideas!
I do have a theory as to why this cameo is receiving a lot of hatred from us. If for example, it was in a new Jedi Knight game, people might say:"Hey, JK, that's cool."
But it's Galaxies and we all know how a lot of people hate Galaxies (with good reasons).
