When it comes to TikTok, frankly I'm not sure if a foreign business under the thumb of the CCP is more or less a threat than businesses operating in our own country abusing the same freedoms for personal gain. You would assume those abusing the system located in the US had a vested interest in stability of the country for continuation of their lofty positions in society, but given broad anti-consumer and labor practices, both foreign and domestic are gutting the foundations of the social contract that make citizens want to believe in and support a democracy.
I think the biggest blow we've had in this country is widespread undermining and exploitation of its citizens for personal gain, which have left many unable or in some cases, unwilling, to support the continuation of the system being used against them.
