I get puzzled why @jack share this apparent hit piece against #Signal Private Messenger. There must a valid reason from his side which I miss here. 

The integrity of the directors of an organisation are crucial for a security product no doubt, but there are other ways to check the integrity of an open source software. 

To repeat, the atmosphere at the top level leadership of Signal has been alarming to me since Moxie Marlinspike, the original developer sort of left Signal.
