The leader of an organization that has a large impact on society, and potentially will have a very large impact on society and the world, being secretive is concerning and suspicious, yes.
Edit: Why? Because the public should know the people who have significant amount of influence in society.
The public doesn't know about Diffie Hellman or Brian Acton or Mike Schroepfer or Alex Halderman and yet here we are.
What else do you need to know about Moxie Marlinspike or Matthew Hodgson and Amandine Le Pape beyond their technical blogs, opinion blogs and conference appearances and the products they put out there ? To decide what ? What does it change regarding their work being done in the open ?
If you suspect them of something there's nothing in the world that they could say or put out that would convince you they aren't... what ? Why is being secretive suspicious and concerning ? What are you suspecting ? You already know more about their name and what they do and think that people who worked on covid vaccines and that has a significant amount of influence and society.
