Let's do some math. Some searching suggests the average size of an e-book is about 3 MB. 82 TB means they pirated about 27 million e-books. At the rate of Russet's fine, that would come to damages of $2.2 trillion. So not more money than has ever is about 4x Meta's entire market cap.
I hope the book publishers sue Meta and end up owning Facebook and Instagram. Not that I expect one evil megacorp to inevitably fix all the ills of another. But it would be hard to make Facebook any worse than it currently is.
