Okay thank you for your input @kevinsarpei but "backed" is quite vague, but I understand your concern. Personally Im more worried about private companies or other actors stealing or buying your stolen information from these "socialmedia companies". In Mexico there have been kidnappings where the victims have been targeted using information from socialmedia etc, this is not uncommon...
Cheers!

What I meant by "backed" is that it's funded by the government ;)
hhaha glad i saw your comment and doh!!
