Gawker exploited this loop to a degree by skipping #2 and we've seen how well that turned out for them. However, it was largely their own hubris that created the problem that might sink them (Hulk Hogan). Most of the rest of the lawsuits they were able to bat away.
As much as I'd prefer some actual firebrand journalism which is willing to report with less verification (in regards to the people in power, not the general population), I can understand caution.
