Reading that article, details that I'm seeing for the second time, I'm reminded of the fact that the arts scene in the U.S. has often been built on the cult of personality of usually one figure. Even at some of the most esteemed institution there is often a centering around one man (it's overwhelmingly men who run the most esteemed arts institutions). NYCB is probably one of the most extreme cases, but only because most institutions and companies have at least one heir apparent waiting in the wings to take over when the person in charge steps down.
This article also makes me think of how famed choreographer Bob Fosse was said to harass many of his dancers, some of whom seemed to excuse it as him being needy. I wonder, though, if you were to talk to those former dancers, in the context of today's #MeToo movement, would they feel the same? Needless to say, that upcoming biopic about Fosse and Gwen Verdon (who he cheated with and cheated on) should be interesting.
