The irony in the whole situation is, as I see it, that we all make up and maintain a system in place which then we are trying to play a game of hide and seek with.
I would argue that even by buying all our fancy electronic gadgets which may be used by this very system to breach our privacy, we are contributing to maintain it.
By all means, we could use dumb phones, dumb TVs, hardened whatnot, sealed off whatever but at the end of the day all these measures are just for alleviating to some degree the symptoms of the “disease”.
To cure from it, if it is possible at all, is a whole other discussion, beyond the scope of not only this forum, but also beyond what many people are willing to discuss, lulling in their sweet dream of living in the best of all possible worlds.
