Scrum doesn't even have managers and doesn't specify any particular tools so I'm not sure what you're basing these claims on. By "the reality of scrum" do you mean that the way it's actually practiced in some teams is "far divorced from its claims" (probably often true) or do you mean that the framework of scrum is inherently flawed even if practiced as designed? You haven't made a case for that.
