That website is one dense concentration of crazy. Each of those links is to yet another article by the same guy where he does some ranting, then mostly misrepresents some aside in an article at another source, then "just asks some questions", then closes with some more ranting.
Which contains the same kind of information they are talking about:
> They're influencing governments in lots of different ways — and corporations, and really everybody else in society, and it's not just about writing checks
So clearly this isn't just a philanthropic effort - it's a political machine with real influence.
