Point of the post is not whataboutism saying that China blocks Facebook and Google and therefore it's fine that the USA does the same to Tok Tok.
Tik Tok User data is inherently a privacy and security risk to the CCP as
Point of the post is that it is factual that
1) all companies are subject to regulatory bodies in their local market (see what has already happened before to Byte Dance and regulators AND
2) China has chosen to implement laws that give companies no choice but to hand over data
eg Two pieces of legislation are of particular concern to governments — the 2017 National Intelligence Law and the 2014 Counter-Espionage Law. Article 7 of the first law states that “any organization or citizen shall support, assist and cooperate with the state intelligence work in accordance with the law,” adding that the the state “protects” any individual and organization that aids it.And it appears that organizations and individuals don’t have a choice when it comes to helping the government. The 2014 Counter-Espionage law says that “when the state security organ investigates and understands the situation of espionage and collects relevant evidence, the relevant organizations and individuals shall provide it truthfully and may not refuse.”
