1. She signed a multi-year deal with Warner, this is where I'm assuming the money is coming from - I don't know what she has done, I'm not a fan or a follower. I assume that those checks aren't thin.
2. She has a deal with Youtube Originals.
3. She has written a NYT bestseller book. Typically not thin checks.
4. A University teacher can make 6 figures, especially if you are famous.
5. You know nothing about the profit she made from her last apartment.
6. A house for 1.2m with a 200k downpayment, good credit requires about 4k/month in total, that is 2k each. Recommended income about 150-200k split between two people.
As I said I know nothing about this person, except what I quickly googled when I read the article. You jump straight to conclusion that it's embezzlement going on, I think more like a court, first I have to discard other possible sources of finance. Which I can't.
Now of course Point 1-3 are on the backdrop of her being the "founder" of BLM, so in any event she is making money of the cause. But that is not equivalent to committing a crime like stealing from charities, morally bankrupt perhaps. Or maybe one deserves whatever they can make on the back of something good, like any famous civil rights advocate that made bucks writing books. Or musicians for that matter.
