People didn't hate Brock as a person as much (though many did), but more what Brock stood for. They hated that he came from WWE, that he was a heel, that he was promoted so quickly (got his title shot in the third fight, was hailed as the best fighter on the planet extremely quickly etc.)
Bones' hate is all about what he is as a person. Whether he is fake, or a genuine psycho, that's what people dislike.
