"The chinese government use tiktok for propaganda" is an effective call to action. Once you form an opinion on tiktok, the FB equivalents will start to to stand out.

The CCP use tiktok for propaganda. Lobbying firms & individual candidates use FB for campaign. In terms of transparency, manipulativeness, political impact, morals and such... not that different.

Tiktok made sure to suppress HK protests, because they're directly controlled by the ccp. Many US firms (eg NBA) were also influenced by the CCPs desire to suppress support of the HK protest. Tiktok hired and greased many Democratic & Republican "staffers" to lobby for them. They grease pockets. Don't all large companies do that? Tiktok shares your data with the ccp. Facebook sells your data, sometimes to political actors. Meanwhile, the NSA help themselves.

The differences between tiktok and FB may get a ball rolling. ITLT, the similarities will come into play.
