You decided to mistrust an entire global organization because one guy duffed an interview? Its spelled out clearly in the article: WHO membership is only given to countries that are members of the United Nations - which does not recognize Taiwan - or whose applications are approved by the World Health Assembly.
Yes the WHO is likely mistreating Taiwan, but its based on the UN and global politics, nothing else. China isn't controlling the WHO. China is just a major player in geopolitics whose reach affects the UN, which affects the WHO.
