In the definition of bankruptcy, you don’t have to pay anything, just have your liability (debts) > assets (ability to pay).

So No, it doesn’t matter if she’s paid it or not. Just being asked to pay in a way that is defensible in court, could make you bankrupt.

This liability would most likely prevent Sarah from getting a new loan (for example to move away from it all). And in theory bankruptcy means not being able to fulfill existing liabilities-which Sarah is most likely not able to.

But practically Meta probably wants Sarah to not publish the book. Sarah may get even more money from another deal with Meta :)

Surely it matters as to whether or not the headline is accurate or misleading.

i guess, but the headline IS accurate. The top-level comment is just spin, it doesn't point out anything that is misleading or inaccurate about the headline.

It's pretty common for technical people (and corporate PR) to misunderstand how the machinery of the judicial system can be used and abused.
