If you can tell secrets to who you please and sell them on the internet, they aren't secrets. Somewhere in the middle of what you're saying, the secrets stopped being secrets, but you kept using the word as if it still applied.
Facebook isn't a group of associates trading anecdotes about their friends: the server guy has never met Mark Zuckerberg, and they are not "associates" in any meaningful way. They're not friends, or even really allies: Facebook certainly has shown inconsistent concern for the well-being of its workers. So let's also drop the "associates" terminology: these aren't "associates", they're employers and employees. Employees aren't acting as individual humans on their own behalf, they're acting on behalf of an organization.
Putting aside the rights conversation for a second, let me ask you a question: if you tell your friend a secret in confidence, and they turn around and sell it to anyone on the internet who will pay a low fee, that would be pretty screwed up, no? We don't even have to talk about rights here: this is just screwed up behavior, regardless of the rights conversation.
A group of people sure, but corporations are not people.
