Silent Circle's response to critical security vulnerabilities has been *extremely* bad. They recently quietly fixed numerous critical vulnerabilities that could lead to a full compromise, without informing their users or submitting and advisory in any way.

Pointing to the vulnerable code on their GitHub led to both myself and Arturo (from GlobaLeaks) to be censored.
