You don't think there's any inequity between somebody with a couple million in the bank and google, or any conflict of interest between my desire to talk about my work and my employer's desire that I do not? Your position is valid enough without being willfully obtuse.

Once you agree to not talk about it (as part of the employment terms), then there is zero conflict of interest.

"Yes, I agree to not share internal info, in exchange for this money. And by the way, I will still share internal info, because inequity."

You're thinking about employment contracts like an abstract economic exchange between two free parties, which is very micro. Try thinking about it instead like a bargain with the (macro) devil.

In other words, consider someone's perspective who has society split into two camps: the people who do all the work, and the corrupt elite that make their living through theft and oppression. In such a world, signing a contract with an employer (i.e. capitalist i.e. elite) is more of a practical step than a sacrosanct bond. There's a level of "what's reasonable" and "what legally enforceable" beyond the basic "never break a promise" level you're working at, IMO.

No ones endorsing publishing trade secrets randomly, but you're treating all disclosures like they're equivalent.

Yet for some reason OP and everyone here are supposed to care what YOU think?

I'm not suggesting people shouldn't post thoughts and opinions. This is about whether a personal desire to self-express, should override their explicit prior commitment/promise not to do so.
