I've been inspecting this topic quite a lot and I'm a little confused now. So, we have reasons not to use Signal, reasons not to use Matrix, there were also some claims about Session being a fraught. Briar is mostly activists related (not very suitable for daily use), XMPP lacks good clients and suffers from fragmentation of protocol standards implementation, SimpleX is too feature-incomplete (no UnifiedPush support, big battery drain on Android, very decent desktop client without any message sync). I can't say a lot about Threema or Wire, as I'm not very familiar with them.
So, my question is — is there any good private messenger at all? What do you think is the most acceptable option?
EDIT: In addition to my post:
All messengers have their flaws, I'm well aware of that. I was interested in hearing users' opinions regarding these shortcomings, not in finding the perfect messenger. I may have worded my thoughts incorrectly, sorry for that.
PGP is unfortunately one of the only reliable ways to get encrypted messages into and out of China. Most of that article is kind of nitpicking IMO. The only major cryptographic issue is lack of forward security. The rest can be dealt with if you have a bit of know how.
Sure, I see where you are coming from. I used to be in favor of PGP as well, but I think I just was conditioned to it because it was everywhere, eg Linux repositories. The argument I found more convincing in this article is that PGP is a swiss-army knife. You might want to use it in an emergency, but professionals have special tools for each different task. In fact, the article suggests very nice alternatives for each task: Encrypt with age , sign with minisign. Two different tasks, two different tools, no need for a web of trust. Just for the arguments sake why do you think that PGP is worth it given the burden of entry?
