Good point regarding the exclusion of scientist outside the WHO organization.

From https://www.nature.com/articles/d41586-020-03402-1:
"But Christian Drosten, a virologist at the Charité hospital in Berlin, notes that invitations to apply for the team were only sent to members of the WHO’s Global Outbreak Alert and Response Network (GOARN), a closed group with experience in outbreak response. Many researchers with relevant expertise were not given the opportunity to apply, says Drosten, who received the e-mail, but missed the invitation while on holiday. “They could and should have issued this as a more open call.”

This begs the question of how transparent can this really be? And how free will any participating scientist feel to question the group's findings, seeing that it could result in the loss of their job?
