For every person who is "super rich", thousands, if not millions, will go through strife and unfair hardship

Oh, I never knew Signal had such humble beginnings. I think you would be very surprised if you ever give it another shot. It's pretty much "install an app and talk" (with the pretty stuff!]). Never heard of SimpleX, might give it a look someday. Thank you!

Even if fake, is there any problem using it if I don't download anything or introduce any login information?

Honestly curious, what was missing on Signal and what was complicated? I can't even remember the sign up process and never felt I was missing out on features, at least not on features available elsewhere
