I've learned that I only mention GOS with family or friends, when security and / or privacy is the topic. I myself never set either of these topics, because this makes any discussion a waste of time.
It only happened once that a friend, who happily used every convenient google service, approached me with the wish to live his live as google-free as possible from now on, but with the wish to have privacy friendly replacements instead. Since I'm no expert for this (I don't want speech commands etc) I couldn't help him really.
What I want to say is: This is am incredibly difficult topic! The best thing we can do imho is to let people know that we are there to give guidance whenever they chose to live more private and secure in the online world.
