The accusations aren't "towards anyone who dares question her", they're towards people who assume that she had come in after the fact and unfairly got into somebody else's role, which is ignorant (and easily cleared up by glancing at a Wikipedia article) and also a common refrain aimed at any woman in any position of authority.

I'm not a fan of Baker for many reasons, but "how did she even get that role?" always pings my shithead radar, and isn't a question I hear for incompetent male CEOs, who are assumed to be just incompetent, while the women are assumed to be incompetent infiltrators who were hired on the basis of their sex.
