I wouldn't say Jobs has been "inviting people into his private life". He has remained fairly private.
I did say "he's granted the media many levels of access, from photos through interviews, to boost his products." Just look at all the magazine covers he's had. The accompanying stories always mix a little of the personal biography -- the arc of his life -- with the product/business news of the day.
But also, consider the 2005 commencement speech he gave -- which I wouldn't attribute to simple PR machinations for Apple, but because a distinguished public person was invited to talk, and wanted to share his insights with the future. He talked about the circumstances of his birth and adoption as a baby; his college years; his exile from Apple; his pancreatic cancer diagnosis and surgery. That is, his life story, as it could help elucidate life choices for others.
The story continues; we're still curious. While it's wrong to pry illegally into private records, and it's wrong to hound him (or his non-public family) about these things, it's natural and keeping with the usual and fair treatment of a public figure to relay major new developments in his life story.
