I'm not sure what "this" you're referring to is, but assuming it's Definers: where did you learn she was involved the entire time? This article says:
Ms. Sandberg [...] asked for the information in an email to a senior executive in January[...]. The email came within days of a blistering speech Mr. Soros delivered that month at the World Economic Forum, attacking Facebook and Google as a “menace” to society and calling for the companies to be regulated.
This seems like a pretty reasonable reaction. As far as I understand this has nothing to do with Definers.
