Because the WEF is not controlled by 52 heads of state of 600+ CEOs. It's controlled by Klaus Schwab, a managing board and an executive committee: https://www.weforum.org/about/leadership-and-governance

10 people sit on the managing board, none of them household names: Børge Brende, Mirek Dušek, Julien Gattoni, Jeremy Jurgens, Adrian Monck, Sarita Nayyar, Gim Huay Neo, Olivier M. Schwab, Saadia Zahidi, and Alois Zwinggi.
