What did they use?

Yeah I signed up for the wait list a while ago but no news

I'd love for something like WeChat to be a thing outside of china

(without the blatant violations of privacy lol)

Yeah I get that. It also is dodgier lol. Some of the type of people that use telegram are hella suspicious

Number 1 is what my question is about

Whatsapp also has scammers

It's just as easy as Whatsapp if you don't want/need to look into more features.

What I'm asking is why is everyone on that platform already when they have better alternatives

The difference being that money is finite and digital media isn't.
