That's why I was there already, along with a few of those friends who used to be part of various WhatsApp groups as well - and they've convinced large groups of pissed off WhatsApp users to download and use Signal today.
I don't know how many of the new Signal users will stay (there's already discussion in one of the new Signal groups about "Why aren't we using Telegram instead?")
Same as much of this thread - these people are not concerned much at all about encryption details, they're largely a pissed of mob of people departing WhatsApp. And some of them are already saying "there's no web client! I can't use this!!!"
I suspect I may well end up back being "the guy who's not part of most group chats" if/when they decide Signal isn't for them... And I'm OK with that.
