Unsure I'd agree. It looks like Amplify is providing you with all the components you need to build on top of all AWS cloud services.
I particularly like their approach which makes it easy to use AWS but the ability to move away from AWS should you want to.
"AWS Amplify is a JavaScript library for frontend and mobile developers building cloud-enabled applications. The library is a declarative interface across different categories of operations in order to make common tasks easier to add into your application. The default implementation works with Amazon Web Services (AWS) resources but is designed to be open and pluggable for usage with other cloud services that wish to provide an implementation or custom backends."
