As a European, I find it quite outrageous to demand a company be sold to the US because it is too successful and valuable to be foreign-held. It is the old-school imperialist school of thought. If you think Bytedance is harming Americans, despite following american law, then amend the rules for social media companies. Or at least be honest enough to say: "The free market is great, but only if we hold all the cards".
Why are you looking to the US for your outrage, EU members are doing the exact same thing: "Eleven EU countries took 5G security measures to ban Huawei, ZTE " https://www.euronews.com/next/2024/08/12/eleven-eu-countries...
To me this makes more sense since a back door in network infrastructure allowing governement communications to be intercepted is far more serious than some kid using TikTok.
