One benefit of that is that you can't take work home, although I think Covid is forcing them to make some changes.

If you leak from NSA they either attempt to assassinate you, or you get put in prison. Due to the massive illegal spying programs run by the NSA, they have lots of avenues for finding out who leaked the data.

If you leak from Apple (and they find out) then Apple can sue you and maybe get a civil judgement against you take your assets and possessions, but you remain a free person.

Huge difference.
