Don't forget that they're also functionally structured. The managers don't own products or features, they manage functions (engineering, sales, design). And in practice, they usually only manage people, with little control over the function. So the managers aren't particularly interested or tied to shipping product features. The PM maybe, but they don't have reports or own much.
