First: Sharing experience by Speech/Talk is a Human Right ( Freedom of Speech ). Not a NDA, not SE has the right, even by agreeing to the NDA to take this away. Because if a NDA has such a sentence in it, its illegimitate just because of the laws. You cant "temporarily" agree to have your human rights ristricted. Atleast not in most European Countrys.
1) Being in the constitution of several countries does not automatically make something a "human right" that applies to anyone anywhere.
2) Freedom of speech is not limitless. Censorship -DOES- apply to a point. Do I have the right to go into work places and start shouting racial epithets and slander? Would you like me to come up to your child and start swearing in front of or at them and you? But, but, Freedom of speech!!! No, it doesn't work that way. When you are in a public place, you abide by that public place's rules and standards of order, which brings me to #3:
3) Freedom of speech DOES NOT APPLY to the internet. Your freedom of speech is as much as an individual site will let you get away with. Things that you could post on gamefaqs you would not get away with posting on somethingawful. Things that the KKK would post on their website would not fly well if posted on an NAACP forum. Things that are posted on 4chan's /d/ or /b/ forums would not go over at all well if reposted here. But, but, Freedom of speech!!! Again, it does not work that way. When you post something on a website, you agree to abide by what they say you can and cannot say. If they don't like what you have to say, they can delete it. It's their site, they have the right to. If you don't like it, start up your own site where you can say anything you want.
What does this has to do with anything? SE's NDA governs what they do and don't want said. And if Alla has posts that violate it, SE can tell them to take it off, otherwise they stop giving us shineys. No more exclusive interviews, no more beta keys, no more Pikko and Elmer bringing us news from fanfest...
So tell me, do you think your "right to say whatever the **** I want whenever the **** I want it" supersedes this site's agreements with SE? Do you think that "Freedom of speech" is limitless?
