The terminology in that document clears it up well enough. It is not a big deal to share sales info posted on employee break room walls, or personal observations. That would never meet the standard of "confidential" or non-public information. Sharing it on the internet makes the info even more "Public", and clearly not for unfair personal gain, provided you are not knowingly spreading deceptive information to influence others to buy or sell a security, and potentially benefit yourself.
It was always something I was curious about.
