Why was wrestling cut from the 2020 Olympics?

Wrestling! Isn't that Essence of Olympics?

The IOC executive board decided to retain modern pentathlon — the event considered most at risk — and remove wrestling instead from its list of 25 "core sports."

Something had to be cut so something could be added.

Wrestling, which combines freestyle and Greco-Roman events, goes back to the inaugural modern Olympics in Athens in 1896....

Wrestling was voted out from a final group that also included modern pentathlon, taekwondo and field hockey....

 Field hockey!

The board voted after reviewing a report by the IOC program commission report that analyzed 39 criteria, including television ratings, ticket sales, anti-doping policy and global participation and popularity. With no official rankings or recommendations contained in the report, the final decision by the 15-member board was also subject to political, emotional and sentimental factors....

Wrestling featured 344 athletes competing in 11 medal events in freestyle and seven in Greco-Roman at last year's London Olympics. Women's wrestling was added to the Olympics at the 2004 Athens Games.

So they let the women in... and then they cut the sport altogether. But they leave field hockey... the team sport conventionally thought fit for women. How well did field hockey do in the 39 criteria?

Maybe the political-emotional-sentimental thinking went something like this: In a system that requires performance of the theater of women's equality, how can we eliminate the sight of something that's making us very uncomfortable?
