I am with you all the way. But the amount of people that only use whatsapp for example in my daily life is staggering. I don't think the good guys are gonna win this one in the end.
It is hard not to take a cynical view, that such dissenters will be pursued aggressively by a system that demands conformity. I do recognize the quasi-fascist leanings in modern consumer IT products and their backers.
But, even if tolerated by this larger IT-bound society, can this sort of IT abstention be carried on long enough and made feasible for different age groups and personality types? Can it be the basis for a sustainable, multi-generation subculture? Or is it more ephemeral, a phase someone might go through, like retirement to a quiet cottage...
Perhaps you could come up with some sort of argument for it from Christianity and start a Christian sect/denomination from it.
