2. This isn't my standard. It is the standard that courts across the country use. The majority of states (including California) adopted a less stringent version call the Uniform Trade Secrets Act. Only 4 states, including my Massachusetts, whose version you see above, haven't adopted the act and instead employee their own versions.
3. Tobacco cancer data might be distinguished. First, it is a stretch to find that it has competitive value. Therefore it would not be classified under trade secret. Second, it probably isn't even covered under copyright because facts are not copyrightable, no matter how much effort was undertook to find them.
But I don't really know the facts of the leaked cancer data. I would have to read them in order to determine whether it was legal for it to be leaked to the press.
