Multiple of our project members used to be members of a project where Jonah is the leader (Privacy Guides). They chose to leave because of his behavior. Other members of that project wrote a lot of useful content, and Jonah used the credibility gained from that for personal financial gain and to harm projects including GrapheneOS. Former members of Privacy Guides are building
privsec.dev instead. Using his services is a mistake and gives him power he's going to end up abusing later.
