Question: Why does Wikileaks need a lot of funding in the first place?
Have you ever successfully defended an online network of public servers, protecting sensitive information that almost every government spook agency and top-tier hacker in the world has on their target list?
I can imagine that it takes some cash, on top of some seriously dedicated volunteer effort, especially when your organization has been partially dismantled by psycho ops campaigns, and parts of your sensitive, critical systems have been sabotaged by insiders and need to be rebuilt.
Imagine trying to stay in communication with each other, in a clandestine way, spread out over the globe, and keeping something like that running.
Maybe they need crypto capability on those iPhones.
