So, as I understand it:
Facebook told Cambridge Analytica back in 2015 to delete the data it had improperly collected.
Facebook claims it recently found out that Cambridge Analytica didn’t delete the data.
If those two things are true: why hasn’t Facebook sued Cambridge Analytica?
I feel like that would be a logical thing for a company like Facebook to do, and my admittedly very limited knowledge of this sort of thing suggests they would have a case - Cambridge Analytica has caused harm to Facebook’s reputation, maybe stolen its property, damaged its stock price… those all seem like the sorts of things that make companies file lawsuits.
So, why hasn’t Facebook sued?
Maybe there are simple and obvious explanations, but I kind of wonder if this isn’t an instance of the dog that didn’t bark in the nighttime - that the absence of a lawsuit points to more significant information not yet in the public domain.
