It’s infuriating. Dobby’s whole thing is that he wants to be free. There’s a reason “Dobby is free” is one of the most memorable quotes in the series, or at least his most memorable line.

Dobby still likes to work, it’s why he chose to do so at Hogwarts, loves it more than he does money since he talked down Dumbledore’s offered wage, but he does still insist on a salary, showing he does not want to be a slave.

I don’t even see why it’s necessary tbh. Dobby helps Harry in canon and is always ecstatic to do so. The only reason he doesn’t help more often is because Harry doesn’t know he can call on him until DH.

And he helps Harry not because Harry is his master, but because Dobby considers Harry his friend (it’s mutual of course) and friends help each other out. It’s as simple as that.
