I got my husband to migrate to Signal with me, but the only alternative to talking to my parents on Whatsapp is using some russian government-owned chat platform that they recently installed to talk to my grandparents (apparently Whatsapp no longer works in Russia). With those two options, I’m sticking to Whatsapp for now (on GrapheneOS, in a separate isolated profile that is completely off while I’m not using it and has no permission to do anything on my phone)
