Are you asking sincerely, or as a passive aggressive commentary about OP's query? If the former: I think, yes, if whistleblowing can motivate change that would prevent fraud.

If the latter, OP didn't disclose anything about a specific company.

It was a sincere question.

How should I have phrased it to avoid ambiguity?

You can't, because sarcasm is a thing and it's often impossible to detect in writing from people you don't already know.
