There is no concrete evidence of spying. Tiktok is a private company. Yes one or more people in Tiktok may have ties with CCP members. But doesn't banning the whole of Tiktok, without concrete evidence, based merely on some level of association with CCP (and the level of association isn't even clear or proven at this point), then how can people still claim "the Chinese people and the CCP are separate"?
It seems more like we're moving more and more towards "anything and everybody from China equals CCP and the whole of China is evil".
