That's true. But there must be a meaning for keeping this minus sign. I have seen Hubbard's original paper. Surprisingly that paper does not have this minus sign!
WebFurthermore, the hopping amplitude is predicted to vanish at a special value of the chemical potential in the topological insulator, allowing the phase diagram to be studied as a function of the ratio of interaction strength to hopping amplitude.
