If it was only $20M, they probably just would have paid it, avoiding riots. What caused riots was their unwillingness/inability to pay the $32B they had inadvertantly promised.

I think the $32B is appropriate in the headline, it's the number that they accidentally promised, and could not deliver on, causing the riots.

But yes, the headline is written in a way to attract clicks, as all headlines are these days. I might have written it slightly differently. I don't think it's especially misleading.
