Different things for different purposes. That food industry chart shows you how a few players control many of the major brands, so it makes sense to be dense and show the brand logos. This is trying to show how many pies Amazon has its fingers in, and for the vast majority, nobody is going to recognize any logo, and using text would make a chart like the food industry one hopelessly busy and hard to read. As it is, that food chart is really only good at conveying one thing since it doesn't clearly differentiate groups of ownership form each other, which is consolidation of an industry into a few large companies. That doesn't even make sense in this case, as instead it's trying to show the reach on one company.
