I wonder how hard they would press an estate. It’s bad PR to go after widows and surviving children, and the data has already escaped.
This is something they’d want to settle quietly, so the family would have leverage.
They’ve made so many terrible decisions already. Going after widows wouldn’t change anything.
I wonder how hard Google could press an estate. For a living person the main consequences would be criminal, not civil, but you can't go after a dead person criminally. Civilly it's not really clear to me that Google would have been harmed enough to create noteworthy damages.
The book publishers might actually be the bigger problem. They'd have civil copyright infringement claims with giant statutory damages.
