I'm not sure. For example, imagine a whistleblower uncovers government illicit activity - instead of deporting illegal immigrants, ICE gives them fake IDs and passports and moves them to a new area to restart their life. Considering the polarization around enforcing immigration limits, that kind of whistleblowing might be seen as a negative thing by a lot of people. You could probably draw similar stories around any other currently illegal but largely accepted activity - e.g. imagine a whistleblower uncovering that a police department doesn't charge people with possession of marijuana. It seems to me that whether you consider a particular whistleblower a "positive" depends on your political stance on the illicit activity they were uncovering.
