Given they are operating in countries like the EU, US, etc and they are doing the same privacy violations and actions like what Facebook did years ago but worse, and even after regulations such as GDPR, CCPA, etc and Facebook was fined in the billions by the FTC, TikTok should be no exception and must be fined in the billions for this invasive and repeated privacy violations.
Nothing has changed, even after the invasive tracking done by Facebook, and Instagram.
