Zed's book is concretely about introducing programmers (particularly new ones or ones going from higher level managed languages down into C) to where and how C can be dangerous especially around string management.
And that's why this is a style issue. Even if he disagrees with Zed's approach (and in particular how undefined behavior is discussed) it's just mendacious to claim that Zed isn't introducing his readers to the idea that one needs to be careful with strings and understand what kind of inputs one will receive.
This is a critically different behavior when compared to Ruby or Python where string management is done for you, and coming from the POV of someone who's familiar with those languages... Zed's approach makes sense. Especially when the alternative being suggested is "you absolutely must go read the C spec and K&RC".
