and for what its worth, Jobs did hire a personal investigator in the 80s to find his mother. That is how him and his sister originally met, if memory serves. It is most likely a personal matter that made him not want to contact his father.
It's odd though since the article seems to read as if Steve's mother was pressured to abandon him by her father but Steve's biological father didn't have a say in it.
Only later after the divorce they described Mr. Jandali as distant but that's no surprise after a divorce.
Yeah there's definitely more to the story, and many sides of it... but I guess all that is ancient history and Jobs took it to its grave. No use in them arguing about it after he's gone. Real life doesn't wrap up like in the movies :-/
The article also says that his father abandoned his other children. Give Jobs' friendship with his sister and mother, I can see how that would make him not want to have a relationship.
