If you provide both:
a) a service to earn money from content
b) an algo promoting those videos
then yes, IMHO they pay them directly for the content produced.
- Meta is commissioning or sponsoring rage-bait
- Controversial creators are earning money through Facebook's content monetization program
The title is ambiguous (at first, I thought it was the first case), and that's where the clickbait lies.
No doubt that also the second case is a serious problem, but that's orthogonal to the ambiguity of the title.
Contrast it with something like Elsagate. Google actioned the offending creators and attempted to deprioritize the kind of content that caused the controversy. Facebook would do the same if they didn't condone rage-bait.
