Angular: Where is the code for the <foo/> component that is used here? Anywhere in the codebase, maybe defined multiple times, depending on module configuration one or another may be used. Good luck finding which one.

React: Where is the code for the <Foo/> component that is used here? Either defined in the same file or imported, like any other javascript thing.

But React is the crazy one.

In modern day Angular, everything is standalone, so the module issue doesn't apply.

I've been coding in Angular since 2 and I have never had a duplicate component with the same name. Almost every Angular app uses nearly the same folder structure.
