Switch statements don't have to be giant. Hint: you can still extract each branch to a separate function / module. But what is more readable about them is the control flow: the condition is explicit and all targets are easy to find. A codebase using switches/ifs and function calls can be easily navigated with ctrl-click in most IDEs. A codebase relying heavily on interfaces and inheritance cannot.

Yes, it depends on the context. In this case the context is the switch statement described in the https://www.computerenhance.com/p/clean-code-horrible-perfor.... Too bad TFA never mentions it explicitly (other than in the title and in the video). Recently it generated a heated discussion around here.
