I think you should speak up with the expectation that whistleblowers don't do well, but with the knowledge that science corrects only if scientists correct it. It's unlikely a single person can take down the culture of an industry, but one person can certainly start a movement. You're definitely well justified in feeling torn about this. I agree that leaving in silence is not the best idea, but I certainly wouldn't blame you if you did that. It's hard to take action.
