"Meta, which owns Facebook and Instagram, secured an emergency legal order on the eve of publication preventing her from publicly discussing aspects of the book, and she faces fines of $50,000 (£37,000) each time she breaches the order."
You might find it surprising that an executive signed a long-lasting non-disparagement agreement, but obviously they wouldn't have got the job otherwise. These are a very real problem. Especially the use of NDAs to cover up gross misconduct.
(a particularly egregious example: Neil Gaiman!)
People are probably too young to remember the "Spycatcher" fiasco: https://en.wikipedia.org/wiki/Spycatcher
Why would a judge pre-decide that any possible word or nod from the author would break an agreement, and consider that valid enough to remove someone's freedom of speech?
Not that any of this matters, these people are too wealthy (and thus powerful) to bring to justice.
