Yeah, I really liked Google's internal openness too, but the way they protected it felt a bit overzealous. As if I'm live-action roleplaying a spy organization or something.
Almost nobody seemed to have any problem with it, so I guess it's just me. ¯\_(ツ)_/¯
The alternative, where people don't share information internally because they're afraid of leaks, is pretty shitty.

Another alternative is to work in an organization (most likely not a private company) that does not care about leaks. Non profits, administrations, many people work there and love it.
