Honestly I understand OP, I also run GrapheneOS but most of my social life happens on whatsapp and I know it's stupid but I can't change dozens of people's choice to install Signal, even though most of them know the issues with Meta.

My hope is that one day or another whatsapp will enshittify so bad that people will be more prone to move to Signal in the same way that recently Windows got so bad that many users moved to Linux.
