Where do you see something about a shakedown in the article? Do you assume that “rather than to use its substantial means to do anything about it” is a shakedown? It sounds to me like they mean taking action with the estates resources to combat Antisemitism, not a naked demand for money which is what a shakedown is.
Demanding someone else do something in your personal interest then inferring negative consequences should your wishes not be fulfilled IS a shakedown.
