it loses trust with customers when the simple setup is flawed.
S3 is rightly built to support as much egress as any customer would want, but wrong to make it complex to set up rules to limit the bandwidth and price.
It should be possible to use the service, especially common ones like S3 with little knowledge of architecture and stuff.

S3’s simple setup (which denies all public access) is not flawed in the manner being discussed here. Allowing public direct access to an S3 bucket is a supported option, but for years has been both non-default and strongly recommended against.
