Have they really? It is the sort of thing you see a lot in fiction but not on reality.

Its fully possible to tip a journalist or regulator these fays with a level of anonymity these days.

And what if they can tell from the information leaked who leaked it? This person's life will be destroyed by armies of lawyers. Just so some journalist can report on something that'll be out of the news in a few weeks and change precisely nothing.

True.

That is always a risk when someone does something in the public interest. But doing stuff for the betterment of others at risk of your own lifestyle is a noble endeavour that many have undertaken despite these reasons.

My point is that others are not bettered by this action, because the action of leaking to a journalist no longer improves anything. Just as it hasn't the last few times this happened. It is arguably a good idea to sacrifice something for everyone's benefit, but it is always a bad idea to sacrifice if nobody benefits.

I can fully imagine not wanting to run the risk regardless however.
