Nobody was trying to stop Gawker from breaking important news, or any other kind of news. That's a false narrative driven by journalists who want to be able to do anything without oversight.
The issue wasn't that Gawker published that Hogan wasn't having an affair.
Again: the story wasn't the issue. The story didn't go to trial. The jury was not deciding whether Gawker had a right to publish the story.
The issue was Gawker publishing a sex tape to go with the story.
