I agree something like this should be released to the public so they can decided if they want to use or not use this program, but to be honest with you if they don't want to encrypt it ok!
People need to start taking a realistic view of things. One the government most likely could careless. There only some many resources at any governments disposal. Just because they can or could do something doesn't mean they well. This narcissistic view by people about everything is getting as bad as the PC.
Most people most likely use a chat like this to send nudes of them selfs are talk about dirty things to each other. Both I highly doubt is a priority for the government! They might also use it to talk about there date or what they had for dinner are there ear infection! Once more no one cares other then the other person on the end of the chat... they most likely dont care either! There just saying they do as not to be rude
Most corporations and just people in general dealing with serious information are most likely going to use there own secure systems. There sure not going to rely on a app created or owned by facebook for such communications.
That said cause i know already getting voted down but what ever I really don't care. Instead of focusing on privacy for what I would call simply stupid things! I want privacy for important things like wireless encryption inside homes and business and laws on how information obtained could be used.
I want strengthen encryption and privacy where it counts! IOT devices! and hardware. Routers, tvs, computers, etc. These are devices that should be truly secure not from someone collecting data about XYZ to show you do YZX on your computer. Real security that stops a hacker from gaining access to your pc or device to install some type program to cause it to become corrupt are be used to attack another system.
