I’d argue that Starbuck’s drip coffee isn’t really their main/default/standard product. Most people who choose Starbucks over other options are going for the “bucket of milk with a little espresso” drinks, their drip coffee is more of a “I want to stay in this café for a while and spend as little money as possible” option.
Starbucks regular coffee is drip, not espresso.

It’s been a quarter century since I worked for them - but our most common order was definitely drip coffee at the time.
