Earlier quoted context omitted.
Last I checked Signal's UX was worse enough that I'd be fighting a real uphill battle to get my friend group to switch.
That's reasonable, I suppose I'm lucky to have a friend group that universally prefers open source sorftware to good UX -- there was never really a question for us.
I have and use Signal with some friends, but there are also loads of people I communicate with who couldn't even tell you what open source software is, let alone articulate a preference for it over good UX.
Are all of your friends software engineers and/or technophiles?
