In China, you can’t exist without a smartphone, because for all existential things you have to do (paying bills, buying tickets etc.) , you are forced to use the almighty wechat app. Smartphones are a tool to manipulate and to spy on the population. It is a tool utilized by the ruling class, to control the masses. I hate the future and I hate “progress”.
Push for mobile phones that have open source operating systems like GrapheneOS. It’ll probably be the most secure and private device you’ll ever own. Then the issue is making these proprietary systems like WeChat, Google Services, whatever China uses. These should be accessible, and if it’s required for day-to-day life then you’re entitled to know every line of code you’re forced to rely on.
