I lump them together because their primary skills are charm and persuasion rather than hands-on subject matter expertise. To me, it doesn't matter whether the end result turns out to be fraud or incompetence, they get ahead of honesty and competence by being phony smooth-talking salesmen. Like a role playing character that puts all their skill points into "Charisma" and nothing else.

And it's not just high profile entrepreneurs. Everyone knows people like this, they're all around us, climbing the corporate ladder. Mediocre performers, but boy can they "look the part", flash a big gorgeous smile, and talk in ways that sound pleasing to leadership but are ultimately empty words.
