The question at the trial will be whether a reasonable person would have believed the evil corporation authorized the requests. You seem set on replacing the evil corporation with society, interposing a sort of "it's a public good for this information to come out, and so we'd generally authorize it". But if the company itself clearly wouldn't have intended you to have that access, and you knew that, and you used the access anyways, then yes: you committed a crime.

Again: mere ToS violations are not enough to cross that line.
