Jobs' terrible attitude is at this point widely known, dissected and discussed to death here and everywhere else. Calling it out does not adding anything new or insightful to this discussion.

His terrible attitude is also entirely orthogonal to his product management sensibility. The fact that he was a jerk does not mean he must be generally canceled and his unique product development theory and insight ignored. The two are not directly related, and it is possible to appreciate one while condemning the other.
