This morning the ACLU announced that it had convinced the government to remove a ridiculous gag order on a subpoena that had been sent to Open Whisper Systems, the makers of the popular Signal encrypted messaging app, and whose encrypted communication protocol is used by many others, including WhatsApp, Facebook and Google for their encrypted messaging offerings. It‘s not that surprising that a grand jury would issue a subpoena to Open Whisper Systems demanding „subscriber name, address, telephone numbers, email addresses, method of payment, IP registration, IP history logs and addresses, account history, toll records, upstream and downstream providers, any associated accounts acquired through cookie data, and any other contact information from inception to the present“ for certain accounts being investigated. But, of course, Open Whisper Systems has basically none of that data.
