They are comparable in how they work technically and what they do with your data, but this is less true of "which geopolitical overlord are you supporting". I edited my post from "equally wrong when Facebook does it" to "also wrong when Facebook does it" to clarify this. To "see ads targeting you" Facebook has to steal as much of your personal data as is technically possible, map out all your social relationships, and then sell it to hundreds of companies all over the world. In any case, the path from watching Tiktoks to supporting concentration camps is long and thin. Most people are not thinking about this and are just using Tiktok because they like it better than anything else.

How does FB sell the map of social relations and your information to companies?

in that case, using Facebook means you’re helping perpetuate white supremacy through the mass incarceration of Black Americans

Yes, and using Instagram supports the droning of hundreds of people every year based on meta-data.

How exactly does using TikTok help China silence millions of camped Uyghurs? If we all switched to Facebook would their voices be heard?

Do you agree that all Chinese companies (even foreign ones operating in China), state owned or not, has to do whatever CCP wants?

If you do, you already have the answer. If you don't, I suggest you get to know a bit more about China before CCP's alternative facts become the facts.

This is a good one.

No. However you would probably still be able to talk about them on your social media in five years.

I'm genuinely curious if posts relating to China's treatment of Uyghurs are already meeting censors on tik tok.
