alt Hacker News> Review means basically to think/talk about something again
The rest is not part of the definition; critics don't review movies in order to change them.
But just accepting that at face value, making code more readable is a "change." I don't know what you're trying to say here.
To criticize is, basically, to say what should have been different. It is in the past, yet it is still about what should be changed.

Yes and this is exactly what I am trying to say. The author limited what is the purpose of a code review like it's has really this limitation but, in practice, the code review is widely about what you think it should changed on the code by multiple reasons: readability, manutenibility, performance, security, bugs, use cases, test coverage etc.
Making code more readable is just one of the reasons why you want the code to be changed on a pull request, it's not the primary purpose.
