Customer obsession would be things like implementing bill caps on new account creation.
Customer obsession would be NOT shipping buggy, unreliable software like AWS Amplify.
Customer obsession would be CloudFormation-first.
Customer obsession would be not forcing me to upgrade to a paid Support account to report a bug.
The list goes on, unfortunately. I do believe AWS employees mean what they say, but the external reality (IMO) is it takes a lot of time and effort to get AWS to notice their customers unless you're one of the big boys.
