I think their ability to perpetually generate gains in productivity and master client service are the bigger factors of their success. The steamrolling no doubt contributes to the success of certain aspects of the business, but it's doubtful that it's a leading factor. Uber, for instance, also steamrolls rivals and partners but its failure as a company is largely due to the total lack of productivity gains in their business model (where they actually lost the gains available in traditional taxi companies).
