"Some people at Twitter were dead weight" does not logically lead to "therefore all Musk's firings at Twitter are A Good Thing, Actually."
Anyone going into nearly any company and firing 3/4 of the staff is practically guaranteed to result in some nontrivial number of people being fired who were not pulling their weight.
People aren't hating on Musk specifically for firing people. We're hating on him for firing people indiscriminately, treating the remainder like shit (demanding people work long hours constantly is unjustifiable, no matter what you think of the personalities of those workers), and making himself the center and focus of Twitter.
