Time to get serious with E2E encrypted messaging (techcrunch.com)

I currently use Telegram for my friends and family, but have reluctantly come to the conclusion that the UK Government is either reaching agreement for backdoors with messaging services, or is trying its hardest to.

I'm also on Element/Matrix. Before I try to get my contacts to join me on there, should I be aware of any privacy issues or is that a good place to head?

It’s been recently added to FDroid.

No, it has not. A third party published it in an f-droid compatible repository. That might be convenient for someone who happens to trust that third party and manually add it to their F-Droid client, but it is not at all like it being added it to F-Droid.

You can use NTFY with Molly (which has been on FDroid for some time).

This does not refute what I wrote. Unless you only communicate with people who get their Signal app from some non-Google source and they all rig up alternative push notification channels, or every one of them uses Signal exclusively on iOS, your conversations are still tied to Google. Perhaps you have so few contacts that you could achieve that, but most people are not in that position.

network-level metadata monitoring by anyone with sufficient access/influence at Signal or their data center provider (such as a government who doesn’t like encrypted messaging).

This one is just a straight-up lie. Everything on the server is encrypted and no one has the keys except the participants.

Encryption doesn't hide network traffic. Signal's centralised design means there is a single point where that traffic can be monitored and traced to reveal which endpoints are talking to each other, and where, and when.

What I wrote is not a lie, which you would know if you actually understood these issues. Please stop making baseless accusations. You are wrong, and you are being very rude.

If you're interested in correcting your ignorance, I suggest starting with this paper, which touches on some of the issues:

If the paper is too much for you, the linked video does a pretty good job of explaining.

Just because someone else uses Google on the other end does not make it dependent on Google on your end.

you are being very rude.

I'm being rude because you're spreading FUD and misinformation and actively making people unsafe. If you have evidence to prove that Signal has access to all of that information, feel free to share with the class. Otherwise, shut it.

If Signal had access to any of that information they would have been legally compelled to provide it when they were served with warrants but they did not, which proves that you're incorrect.
