@dalias VeilidChat is a _proof of concept_, categorically _not_ real competition at this point.
Cwtch is good to a degree, and probably the best option for highly specific use cases, but in addition to the fact that it isn't available for iOS users (and while you can say users who care about privacy shouldn't be using iOS and be correct, we're talking about actually protecting beings as they exist here, not what they _should_ be doing — especially if that then leads to "well, buy a new phone then", which would be an incredibly privileged take), the Android version is buggy to the point of unusability, and it always has the pure P2P messenger issue of requiring both contacts to be online simultaneously to function.
Add that all up, and you get something that is _not_ going to attain wider adoption, nor be practically usable for a majority of possible users. If you argue that VeilidChat, Cwtch, and Signal are the options, well, that's down to just Signal now, and I already explained why that isn't always usable at all.
The concern about the trustworthiness of SimpleX's codebase is valid, and their code releases should be watched very closely for compromising updates, but saying that an open-source program _is_ unsafe without citation of any specific issues comes across as scaremongering. In particular, I note that throughout the history of the internet, wholly unsubstantiated accusations that such-and-such is a "honeypot" have been _widely_ used to scare users away from secure software so the government can continue monitoring them without issue. I'm not saying that you, in particular, are a fed, but what I am saying is that _that kind of thinking_ is exactly what they promoted and what they want.
