So as I type this, Signal have two stories in top-10 on HN: more coverage of Signal's Cellebrite Hack, and this.
Are they connected?
Signal gets this subpoena on the 29th March, and the reply by ACLU is on the 12th April.
Signal's founder and CEO, Moxie Marlinspike, hacked Cellebrite and the story surfaced this week.
Was it retaliation? Was it just because the subpoena made him wonder? Or is there something else causing Moxie to lash out at Cellebrite about now? Or was it all chance?
