The initial launch post was: https://aws.amazon.com/blogs/aws/amazon_simple_q/
> We’ve got sample code in C#, Java and Perl, and we also have a Windows Communication Foundation (WCF) Add-in.
They launched as API-only, and they gave you sample code for how to talk to their psuedo-rest-like API, and use of SQS was API only.
I don't know when the aws cli launched, but it was definitely a bit later.
They recycled the AWS name for their cloud stuff, and I don't count e-commerse services as AWS, even if they happened to share a blog.
