You can't teach old dogs new tricks.

Something at which even the original Signal fails. It has received criticism multiple times (1, 2) for not being verifiable whether it’s been tampered with by the app’s distributor, and also for having included properietary google services dependencies which dynamically load further code from the phone which is also a security issue. Worthy forks solve both of these.

That's unfortunate. I do hope that these forks don't go and start making extensive changes though, because that's where it becomes a problem.

Seriously, what are you talking about? The vast majority of people don't want anonymity. Obviously Signal isn't cut out for that! The fact is, most people don't care about anonymity.

And what metadata can you harvest exactly from a UNIX timestamp and phone number? Signal can tell who is communicating to who, but they cannot read your messages.

What? How is this a red flag? Having third party clients is not good for security.
