What I find funny about this example is that at first I thought the "it happened" argument was going to be used in defense of the person doing the stabbing. Which, of course, it could.
Whether anybody thinks people "should" or "shouldn't" get stabbed is irrelevant. People do get stabbed. When it becomes enough of a problem, other people do something to stop it.
Gawker went and made a powerful enemy for no good reason. Outing someone who didn't want to be outed helped no one. Thiel used the considerable means at his disposal to ruin Gawker in a way that didn't harm anyone other than the owners of Gawker. Since nobody else really benefited from Gawker's existence it's unsurprising that nobody else really cares if they stop existing.
If Gawker had been exposing powerful people doing something illegal or otherwise harmful instead of just being gay or having affairs, they would have had the justice system and the public on their side and they wouldn't have lost the lawsuit.
