I wouldn't give Mike too much hate like he's an obnoxious douche by nature and a terrible songwriter. I can give him respect that he tried to keep the Beach Boys going after Brian went clinically insane, and Dennis left. After losing your main songwriter, producer, lyricist, and front man, nobody else tried to step up to the plate and keep the band going. Even though it was horrendously awful and he deserves hate because he's a douchebag, he didn't ruin The Beach Boys, The Beach Boys were ruined because Brian was mentally insane and had a terrible psychiatrist to help him.
