Whistleblowers get destroyed in the culture we have right now, they loose everything. It don't think its reasonable to ask people to destroy their own lives so that we might one day find out about the horrors that companies do only to watch as nothing is done to resolve it with the perpetrators.

If the circumstances were different and the public didn't stand for such widespread mistreatment of those that stood against illegal activity then there is different advice, but far from having protections for whistleblowers as it stands we only have punishment.
