Well, some people use telegram cause they find it intrusive or annoying, and for some it could be that it requires a mobile number to set up, which they may not want to make public.
LoyceV actually created an alternative which doesn't require telegram for those that don't use the platform. Link here -
https://bitcointalk.org/index.php?topic=5331343Thanks for adding another alternative, mate. I think with more alternatives, @Eternalman can more wisely choose which one he wants to use. But we have to remember that this topic is not a specific topic to discuss about @Eternalman's question, so I think it's enough to talk about this here.
