For anyone that has had even moderate experience with TikTok comment moderation, it becomes clear very quickly there's an incredible bias that seemingly disfavours Western interests. This includes calls towards extreme violence that should be banned per their own content policy. I don't think you need to have access to any secret documents to have a good deal of suspicion this platform is being used by foreign actors either directly or indirectly to shape attitudes in the West. If freedom of speech is at stake, protecting TikTok may actually be harmful to that cause.
