I couldn't care less if China gets my TikTok browsing history or whatever, they can't touch me. I do care that my own government seems to be rapidly trying to censor and weaponize social media while telling me to stay scared of a nebulous foreign enemy they've been trotting out in the name of authoritarianism since the 1950s. All of our data is already being sent to the NSA and they probably already have root on every electronic device you use, and they still kill people over metadata. Meanwhile someone's Google search/maps history can land them behind bars in some states, just for reading the wrong books or searching for the wrong kinds of medicine, because it turns out inalienable rights are very much alienable.
So yeah. Tell me why I should be more concerned about what China might do, as opposed to what my own government is already doing?
