What's wrong with Starbucks Roasting ?
They simply over roast. To mask the inferior beans I would guess.
Overroasting makes the coffee bitter.

SBUX intentionally is seeking a taste that can be repeated time and

bean over the top in a roast, it takes away the individual
characteristics and gives you a uniform taste.
It's a slight of the hand and a slow move to the roaster. Keeps 'em
