The line about F-Droid doing no automated scanning is particularly troubling. Since he can't possibly imply that a Signal compromise would be detected this way, Moxie is making a political argument against the way people are using F-Droid to install other applications. He refuses - on principle, no less - the right for users to control their hardware and have full control over the software they install, and thinks the walled garden approach should be forced on every Signal user. Sorry, there is no excuse for Signal not to be available on F-Droid. I understand the automatic updates argument if it was valid at the time, but Signal has no right to impose what other applications I run and how I get them.
