So, are you saying this?: That this $500k contract which you still have not produced somehow breaks a law which you have not named and thereby abrogates Facebooks free speech rights and therefore you think that means the US government should control the content of Facebook.
The government should not have the right to control the content of Facebook.
Global Engagement Center (GEC) has contracts with a number of social medias. I've read that google and twitter is part of this contract. If you want to look it up that is great.
I'm looking for an official paper on the list of "silicon valley" contracts. (US State department term)
If you can find it that would be interesting.
