Threema does not have federation, therefore it suffers from the same fundamental design flaw which allows Signal to abuse its position like this.

Does it have encryption yet?

When did it not have encryption?

Forever.

I mean, I think has at least had strong end-to-end encryption since I first heard about it three years ago. What is new as of maybe six months ago is that it is finally open source, but it was always highly secure.

Are you maybe confusing Threema and Telegram?
