One thing, though, is that Virgin never ran a monopoly, but a series of successful (and many failed) ventures which often displaced an incumbent in an industry where consumers were genuinely being screwed (mobile, airlines, to some extent health care).
Bezos is an unrepentant monopolist. Sure, he played the game well, but ultimately built what is now a sticky, foul smelling heap with strong lock-in effects.
Strangely I was much more accepting to see Branson in space. Bezos comment about Amazon shoppers paying for his little joy ride was unadulterated tone-deafness.
