Notice that the journalist changes the topic between the first and second paragraphs:
- "... sharing passwords can be a violation ..."
- "... use of a former coworker's password to access one of the firm's databases ..."
These things are different, and should be treated differently. At the end of the day, the law exists to discourage people from acting like dicks. This guy did exactly that. While I am not a lawyer, the Court seems exactly right here.
