Good luck with that... Way too many things run on the internet nowadays. It depends on where you're from but I'd argue that living a normal life in 2026 without any internet is either super hard or straight up impossible. Of course you lose a shit ton of convenience, but I wonder if there is a roadblock somewhere. Maybe something just doesn't have an offline alternative anymore.
For these people social media is the actual problem not the internet. And since they haven't experienced a life without them it probably feels shocking for a while, they get the urge to become a prophet and spread the word of a great life offline.
