What about the archetype Staff Software Engineer who’s good at creating a promo packet but not good at much else? They come into an org, replace some open source / well-documented well-built tool with an undocumented poorly working tool, then they convince other org members to use this new tool as they actively disable or undermine the existing tool. Come promo time they now have a line in their promo packet “built new tool, drove adoption of said tool to 80%”. At the last company I worked it seemed like a good many of the staff engineers were like this, though may be just the symptoms of a company with braindrain.
