Regardless what the individual has done, it is of my personal opinion that friends should not form part of the firing squad, simple as that. There is an entire community here, hundreds of thousands of people who can lay down judgement, asking Lauda to do it is wrong. I don't blame Lauda, obviously she was backed into a corner and it became her rep or his, but this situation isn't beneficial for anybody.
Almost seems like just virtue signaling if someone has to shoot out a negative feedback after a number have already been sent. Not that it's not fine but just redundant.
Moreover, they don't have to outright send a feedback but they can simply disagree with the behavior. I think the pressure to warrant a neg is fueled by indignant individuals.
