if someone who i don't want to talk to can message me on a "secure" platform just because they have my phone number from years ago then that doesn't really feel great from a security perspective
@calcifer That is precisely why Matrix, with all its shortcomings is viable in non-free countries like China and Russia, but Signal, however secure it might be, is just a shiny useless app.
If you can't trust your cell provider, using your phone number as your primary ID means it can always be traced back to real you. Of course you can use phone number registered to some other person and a burner phone, but it also has its cons and it's not for everyone.
