The TikTok debate has always been about the balance between national security and free speech. We found a compromise. TikTok will remain, all of its national security risks will remain. Also, the law that tramples free speech is upheld by the court, but will be blantently ignored and unenforced. Everybody loses. This outcome is worse than anyone could have conceived.
If social media owned by foreign companies is a national security threat, then wouldn't that essentially make FB, X, YouTube a threat to like every other nation? Why not throw wikipedia in too? So now any nation can legitimately see any other source or collector of information as a national security threat and ban it at will? Taken to the logical conclusion, every nation should be enveloped by its own digital borders.
To me, it's the popular sentiment alone, for example people feeling sad and upset TikTok's gone and feeling happy that it's back, that's preventing this dismal future, otherwise governments would block apps on a whim. And this I'd say is a win.
