Yes, but criticizing someone's work in a single-blind and private review leaves less motivation and opportunity for the powerful to be vindictive.

But outside of physics, there's many fields of science where double and even single blind is meaningless. If you get access to the review directly, you can tell by what they say and how they say it who they are. If you're a vindictive powerful person, who cares that you might be wrong?

Just have to publish reviews anonymously, and if there is outcry about it journals can have internal investigations on the matter.
