While I agree that there's a lot of marketing speak here, I have to note that:

1) You wouldn't expect zero margin, you would expect normal margin, that is, these companies should have around the same margin as the average of the rest of the economy.

2) Commodity markets don't have to be low margin, because a commodity market with high market concentration will be a high margin market.

What does market concentration mean?

I pretty sure it refers to how the market share is spread between the competitors in a market. In a market with low concentration, you have say 20 competitors and no one has more than 10% of the market. When there is high market concentration, 3 of those 20 competitors might have 80% of the market.
