Yes, I have been following Signal and alternatives since... well since TextSecure was only for SMS. And I find that many times people critical about Signal don't really know much about it except for the fact that it uses the phone number (not the email).
Again, not saying it's perfect. Just that for my threat model (which arguably is a valid threat model for billions of people), it's a very good solution.
So you're saying that a "black hat hacker" cannot exist, because by definition a hacker is not a malicious actor. So everyone who is using the word "blackhat" is disrespectful towards those who identify as "hackers", as much as using the N-word or F-word is disrespectful towards the respective communities. Am I getting that right?
