Signal is bad cause its in the US is probably the weakest argument you can use against it.
Its insane how people in privacy forums would always venture into this kind of purity test, giving you app suggestions that will never be adopted by people like my mother. Not to mention calling people 'normies' as if it raises themselves into some shit pedestal they self manifested.
You don't win through insults and exclusion. One person shifting from Facebook Messenger to Signal is a WIN, however you want to frame it or not
