Wow, great article, thanks for the link.
The moment I read the quote from Signal's president, I called bullshit. I was there, working at a company that had massive records, probably of about 1/3 of Americans.
We were very much concerned with this data in private hands. We were concerned about this kind of data in anyone's hands.
Such BS coming from Signal is part of why I no longer use or reccomend the app. I simply can't trust them when they make such blatantly bullshit statements.
Like their reasononing for dropping SMS support because the "engineering costs". There's nothing your app does for SMS, other than to hand the message to the SMS system (technically, it reads and writes to the single SMS database on Android, which was a change implemented in about 2015), using a published API.
I'm starting to suspect the motives after reading such lies.
