I disagree with a section on leadership principles, especially with how leadership is defined here.
My first problem comes when you scan the section headers. When you see "leadership principles", I think many people would think of leadership being close to managerial. But that's not true when you read the first paragraph. If you define a leader as anyone who has influence, that could actually mean anyone in the organization as a whole.
Leadership is an individual influencing a group. Influence comes from power. What is typically referred to as the organizational leadership (the people in charge) is simply the people with legitimate power. There are other sources of power. Being well liked (referent power) or being seen as highly competent in a particular area (expert power) or being seen as holding the ability to make someone's life difficult (coercive power) can allow someone to influence a group.
My point is that any computing professional may act as a leader. Because that is true, calling out leadership principles separately from other principles doesn't make sense. I think it just makes reading and understanding the code more difficult.
I think if this section were to be removed, some minor edits would be required to all of the principles in this section to change the focus from organizations to what individuals have to do. But I think you may see some principles go away since they already exist elsewhere, but the explanatory text moved around and generalized to apply to all computing professionals.
