Facebook, the company, is planning on giving away their entire net worth? Where are you getting this from? Also isn't Facebook worth somewhere in the region of $245 billion?

when FB runs an elaborate campaign to make plebs believe their dear leader is investing his fortune into a charity, when in reality he's invested it into a Delaware based LLC that allows him to avoid Estate taxes....then you start questioning the intent of FB.

It's not "philanthropic purpose" it's an investment vehicle that can be used to do virtually everyone, without scrutiny.
