Non-profit and actually quite economically efficient per user. Once WhatsApp was bought by Meta the writing was on the wall. I moved out of it immediately and I'm surprised people are caught off-guard by this news.

I suppose there's little guarantee Signal won't be sold, but an ultra popular app with no profit, owned by a single bloke (WhatsApp) was the last thing I expected to be a sustainable platform for my communications. Same reason I've never looked at Telegram.
