Same, it's fair to have means of communicating that you just don't want to use - and I let that go both ways as is fair. But if both my boomer parents are ok on Signal (with some initial help with notifications) then it makes it a pretty weak argument when acquaintances much younger than them say 'bro Signal is too hard, I uninstalled it'. For them I say 'No worries: email, call or SMS me if you need me'.
