The fact that you are here on HN tells me: You and your friends are tech savy, most in your age are not :-)
Edit: Regarding monetization -> yes, either carrier billing (if available) or just by iTunes account is much much easier and higher conversion, just becaues of the fact that people do not have to remember their payment details :-D
I can only count two (one offline, my former classmate/friend who we studied together for 11 years from KG to 10th grande) and some other people
I have convinced my same offline friend I mentioned to use Linux, specifically hyprland so its a win :D
> most in your age are not :-)
So I agree in that sense. To be honest. I am saying out of all my friend/peer/former classmate circle, only 1-2 people are some that I consider to be privacy conscious.
