Kind of but it’s not fair to put it all on the manager. Multiple people decided to hire the person. Somebody else approved that code review. People approved the technical design. Why didn’t the tech lead raise concerns with the manager about someone’s under-performance, etc. it’s unfair to just put all blame on the manager.

The idea of extreme ownership is about not saying “not my problem I won’t do anything” or blaming your reports. It’s about saying I can and should do anything and everything in my ability to fix problems.
