You just explained exactly what's wrong with big tech companies.

Application/product developers are seen as less capable and they put their best developers in infrastructure/platform/sdk/libraries.

This is all completely backwards. The application is what generates revenue and what needs the most attention to ensure the tech is a good fit. The needs of the application should be what drives the infrastructure to support it, but instead those companies have infrastructure people call the shots and heavily constrain how all applications should be built.

Thankfully there are sectors where application developers have full freedom on their tech stack in order to satisfy their business requirements and infrastructure is just people maintaining a collection of tooling and services that others can opt in to use or not.
