When I see record-breaking revenue being referred to as recording-breaking profits, I must question the validity of the article: Revenue == Top-line (not profits) Earnings == Bottom-line (profits)

Simply import it into your own code base, and then review it as if it was written internally. Basically, learn it inside out, as if you wrote it yourself. If that is not legally sufficient, then the laws need to be rewritten since the lines they would be attempting to delineate would at this point be completely imaginary. It doesn't matter whose head it originates from, what matters is that it is fully reviewed and completely understood to the point where everyone on your team is prepared to stand behind the entire body of code. If that confidence comes from actual understand, it becomes irrelevant who wrote the code in the first place. How would it be any different if, instead, it was code written by somebody who no longer works at the company.
