Really? Look harder.
I'll try just once more to clarify what I've been trying to explain to you: Starbucks sells a lot of drinks with huge margins and makes a lot of money doing it. Good for them. But their coffee, their regular black coffee/espresso, sucks. That's because they use cheap beans (margins, anyone?) and overroast them to mask the flavor, then encourage people to buy expensive variations with lots of sugar, milk and flavorings (again, margins) to further mask the poor quality of the basic coffee.
They make great money but would be gone in a week if it had to sell coffee. Just coffee.
Your comment suggests you have issues with Starbucks that have nothing to do with the quality of their beans. Why should you care what others do or buy, or for that matter, care what Starbucks sells or how much profit they make? Starbucks was successful selling only beans long before offering drink variations, which by the way, is apparently what their customers want. Don't buy Starbucks if you are so bothered by their success.
